We illustrate how measuring the contrast in the curvatures of the inµ− and µ+ valleys can be used to estimate εµτ. Our method would provide a direct and robust measurement of εµτ in the multi-GeV energy range.

We further note that the oscillation valley in the (E,cosθ) plane of the reconstructed muon observable bends in the presence of NSI, its curvature having opposite signs for µ− and µ+.
A Numerical Study of Oscillations of Highly Magnetized Non-rotating Axisymmetric Neutron Stars
On the other hand, oscillations of disturbed neutron stars are closely related to the star's composition, structure and equation of state. We extract the eigenfrequencies and eigenfunctions of the excited oscillation modes and preliminary results show that the eigenfrequencies decrease with the ratio of magnetic to binding energy of the neutron star, implying a suppression of disruptive oscillations in a more magnetized neutron star.
A Radioacitivity Survey of Commercially Available PTFE from European Suppliers
So far, the numerical study of oscillations of magnetized neutron stars has not yet realized the observed order of field magnitude. Here we present a breakthrough using a multi-frame general relativistic code, Gmunu, to dynamically simulate the oscillations of highly magnetized, non-rotating asymmetric neutron stars with field strengths of 1015−17G under nonlinear perturbations.
A comparative study of Dirac and Majoarana ultrahigh-energy neutrino oscillations in an interstellar magnetic field
One of the important developments in the field of neutrino astrophysics is the search for ultrahigh energy (UHE) cosmic neutrinos (even above PeV–EeV energies), which are believed to be produced by reactions of UHE cosmic rays composed of protons and core. This means that UHE cosmic neutrino propagation can be affected by interstellar magnetic fields due to the effect of spin oscillations [2].
A deuterated liquid scintillator for supernova neutrino detection
One of the main advantages of exploring the UHE neutrinos as astrophysical messengers is supposed to be their ability, unlike the case of charged particles, to travel in straight lines in magnetic fields in space. In this contribution, we investigate the UHE neutrino propagation in interstellar space in the Dirac and Majorana cases.

Aspects of High Scale Leptogenesis with Low-Energy Leptonic CP Violation
Using density matrix equations (DMEs) for large-scale leptogenesis based on a type I see-saw mechanism in which CP violations (CPVs) provide low-energy Dirac and/or Majoran neutrino mixing phase (PMNS) matrix transitions, we investigate flavor regime transitions 1-to -2 and 2-to-3, where the flavor regimes 1, 2 and 3 of leptogenesis in the creation of the baryonic asymmetry of the ηB universe are described by the Boltzmann equations. Focusing on the 1 to 2 flavor transition, we determine the general conditions under which ηB goes through zero and changes sign at the transition.
Astroparticle physics in DUNE with the X-Arapuca detectors
Analyzing in detail the behavior of the ηBin transition in the case of two heavy MajoranaN1,2 neutrinos with hierarchical masses, M1 ≪ M2, we find, in particular, that i) the Boltzmann equations in many cases fail to correctly describe the generation of ηBin Flavor regimes 1, 2 and 3, ii) the 2-flavor regime may persist above (below) ~1012GeV (~109GeV), iii) flavor effects on leptogenesis persist beyond the maximum considered typical leptogenesis rate for these effects of 1012GeV . We show, in particular, that when the CPV is due to the Dirac phase δ, there is a direct relation between the sign of sinδ and the sign of ηBin regions of practical leptogenesis in the case of the light neutrino hierarchical normal mass spectrum; for the inverted hierarchical spectrum the same result holds for M1

Bridging the microhertz gap with asteroids: opportunities and challenges for gravitational wave detection
I will demonstrate that a few carefully chosen asteroids orbiting in the inner Solar System can act as excellent natural gravitational test masses despite the environmental noise sources. At low frequencies, I will discuss how gravity gradient noise arising from the combined motion of the other-106 asteroids in the inner Solar System sharply cuts the sensitivity of this proposal.
Building low background kton-scale liquid argon time projection chambers for physics discovery
Currently, there is a lack of coverage by existing and proposed searches in the GW frequency band that lies between the peak sensitivities of PTAs and LISA, approximately 0.1-100 microhertz. Sensitivity in the middle of this band is mostly limited by various solar perturbations to the asteroid test masses, while the high frequency sensitivity is limited by noise in the remote link.

COSINUS: Cryogenic NaI detectors for direct dark matter search
Today, the situation in direct dark matter detection is confusing: The DAMA/LIBRA experiment observes an annual modulation signal with high statistical significance and fits the expectation of a cold dark matter halo in the Milky Way. However, in the so-called standard scenario about dark matter halo and dark matter interaction properties, the DAMA/LIBRA signal contradicts the null results of numerous other experiments.
CPT violation in neutrino oscillations
To be immune to possible target material dependencies, COSINUS will use NaI target crystals, the same material as DAMA/LIBRA. In this contribution, we will outline the current status of the COSINUS experiment, from the development of the cryogenic NaI detectors to the construction of the experimental facility in the LNGS underground laboratory.
CSIS: a Cryogenic Superconducting Inertial Sensor
The recently published Lunar GW Antenna (LGWA) concept uses an inertial sensor to investigate surface motion as a result of GW excitation of the Moon's body normal modes (fundamental just below 1 mHz and many other modes and their harmonics at frequencies higher). In summary, CSIS will be the world's most sensitive low-frequency inertial sensor and, when deployed in ET and on the Moon, will enable GW science from 1 mHz to 10 Hz.
CTA prospects for annihilating dark matter from observations of nearby spiral galaxies
The cryogenic superconducting inertial sensor (CSIS) revolutionizes the field of inertial (cryogenic) sensing by obtaining a displacement sensitivity at 0.5 Hz of 3 orders of magnitude better than the state-of-the-art. Not only will ET help detect GW from 2 Hz onward, CSIS will also be stationed on the Moon.

Dark Matter Search with the Nuclear Isomer Ta-180m
We investigate how strongly interacting dark matter collides with Ta-180m, leading to its deexcitation. This search has further constrained the open parameter space of the cross-section, mass, and component fraction of strongly interconnected dark matter.
Dark matter Axion search with riNg Cavity Experiment DANCE
Ta-180m is the rarest known isotope and the longest-lived metastable state, whose half-life limit is on the order of 1016 years. The energy stored in the metastable state is released in a transition that becomes the signature for thermalized dark matter in a well-shielded underground experiment.

Data analysis strategy used for the detection of CNO solar neutri- nos with Borexino
One of the key aspects of the analysis is the efficiency and effectiveness of the multivariate fitting technique adopted to separate the neutrino signals from the background present in the detector. This poster will describe all the key steps of the analysis strategy adopted to extract the CNO neutrino interaction rate.
Deep Science at Boulby Underground Laboratory
It was designed and built with the primary goal of detecting low-energy solar neutrinos in real time, and for more than ten years of data collection, it has measured all the neutrino flux produced in the proton-proton chain, i.e. following improvements and developments in both hardware and software, Borexino has delivered the first observation of solar neutrinos emitted from the subdominant Carbon-Nitrogen-Oxygen (CNO) fusion cycle.
Density functional theory calculates general crystal responses for electron-dark matter interactions in silicon and germanium
We test the influence of the detailed description of the electronic structure in crystalline silicon and germanium on the resulting calculated response of the electrons to general dark matter interactions. We show that if the dark matter interaction energy reaches a threshold of about 30 eV, electron excitations of tightly bound germanium 3d states become important and since they are very narrow, they suffer from incorrect electron self-interaction in the local density approximation to density functional theory.
Detecting CEνNS and searching for new physics at reactor site with the CONUS experiment
We then calculate the scattering rates from general crystal responses and place constraints on current experiments using silicon and germanium targets.
Detecting and characterising pulsar halos with the Cherenkov Telescope Array
The newly identified TeV source class of pulsar haloes may be numerous and luminous enough to constitute a large fraction of the sources that will be observed with the Cherenkov Telescope Array (CTA), especially in conjunction with the Galactic Plane Survey (GPS), one of CTAs key scientific projects. CTA will cover energies from 20 GeV to 300 TeV, between those already surveyed by Fermi-LAT and the High Altitude Water Cherenkov (HAWC) Observatory, and will also have a better angular resolution than both, allowing us to explore the radial profile of the halos.
Detection Of Heavy Dark Matter Particles In DEAP-3600
Based on simple models for individual pulsar haloes and their population in the Milky Way, we investigate under which conditions such sources can be identified in the GPS observations, possibly supplemented by additional dedicated exposure. Within the framework of a full spatial-spectral probabilistic analysis, we derive the sensitivity of the CTA by considering both general extended emission and the specific physical pulsar-halo model.
Detection of Core-Collapse Supernova Neutrino at JUNO
In this study, we examine the perspectives offered by CTA for the detection and characterization of such objects. It uses the 20kton liquid scintillator as a target, which enables it to detect supernova explosion neutrinos with large statistics for the next Galactic Core Collapse Supernova (CCSN) and also pre-supernova neutrinos from the CCSN's close progenitors.
Detection prospects for the double-beta decays of 124 Xe
Among them, IBD events make it possible to obtain the directional information from CCSN even in a liquid scintillator detector.

Direct measurement of topological information using HUNI-ZICOS detector for 96Zr neutrinoless double beta decay experiment
To investigate a half-life of 0νββ over 1027 years, which corresponds to a neutrino mass of less than 0.01 eV, we must use the scale of the 96Zr isotope and reduce 95% of the backgrounds. For the latter case, we developed a new technique to use Cherenkov light to reduce those backgrounds using the site topology for photomultipliers receiving Cherenkov light, and found that 93% of the 208Tl decay events could are reduced with an efficiency of 78% for 0νββ events.

Energy-Dependent Neutrino Mixing Parameters at Oscillation Ex- periments
One of the most important achievements in the field of particle physics is the discovery of neutrino oscillations. We also review ground-based experiments and show that the mismatch of neutrino parameters in production and detection can cause large effects on T2K and NOvA.
Engaging the public with astrophysics virtual reality experiences
Despite already being awarded the Nobel Prize, neutrino oscillation experiments still have a lot to offer, mainly the discovery of CP violation in the lepton sector is expected. In this talk, we argue that neutrino mixing parameters in production and detection need not necessarily be equivalent, since such parameters are subject to renormalization group evolution and the process of neutrino production and detection takes place at different energies. In this talk we discuss this in the framework of a UV competition model; in particular, we demonstrate that quantum effects can produce relevant observable effects in various neutrino experiments.

Fast Flavor Ocillations of Supernova neutrinos in three flavors
The necessary condition for the existence of these fast instabilities is the presence of a zero crossing in the angular distribution of the neutrino lepton number. The previous literature on fast conversions focused on an effective two-flavor analysis, where the zero crossing in electron lepton number (ELN) was crucial as the assumption of similar number density of the heavy lepton neutrinos led to similar angular spectra.
Fast neutrino flavor conversion induced by the coherent back- ward scatterings in the core-collapse supernovae

Finally, given the relevance of Migdal electrons to the search for low-mass DM, we discuss some new ideas on how to possibly measure such an effect with detectors based on a time projection chamber exposed to a high neutron flux.

We derive three possible formulations to measure α, based on (a) Nuclear Physics (b) Quantum Mechanical description and (c) Data-driven description[3]. Accordingly, studies of νAel with different neutrino sources provide complementary information and cover transitions from fully coherent to decoherent states.

The description of νAel process in terms of α is complementary to the conventional descriptions with nuclear shape factors based on the many-body physics in the nucleon-nucleus interaction. We found that coherence is mostly complete (α>95%) forνAelwith reactor and solar neutrinos for Xe/CsI, Ge and Ar targets, while coherence is only partial for DAR-π and weak for atmospheric neutrinos.

Neutrino quantum decoherence engendered by neutrino decay to photons, familons and gravitons
Such a violation is called quantum decoherence of neutrino mass states and leads to the suppression of flavor fluctuations. We use this framework to study the mechanisms of neutrino quantum decoherence caused by the decay of neutrinos into photons, familons, and gravitons.
Neutrino theory
In our previous studies (see 1 and reference therein), we presented a new theoretical framework based on the quantum field theory of open systems and applied it to the problem of neutrino evolution. In this paper, we present the generalized framework that allows to consider the quantum decoherence of neutrino mass states induced by a neutrino decay into a lighter neutrino and a massless particle.

Non-standard neutrino oscillations: perspective from unitarity triangles
The invariance of the form of the probability expression (even in the presence of a new physical scenario, as long as the mixing matrix is uniform) allows a clean geometric view of neutrino oscillations in terms of LUTs. Interestingly, the geometric LUT-based approach allows us to express the oscillation probabilities for a given pair of neutrino flavors in terms of only three (rather than four) degrees of freedom, which are related to the geometric properties (sides and angles) of the triangle. .
Nonstandard neutrino Interactions as a solution to the NOvA and T2K tension
Using perturbation theory, we derive the expression for the oscillation probability in the case of NSI and cast it in terms of the three independent parameters of the leptonic unitary triangle (LUT). Moreover, the LUT parameters are invariant under rephasing transformations and independent of the parameterization adopted.

Dark photon as an ultralight candidate for dark matter can interact with Standard Model particles via kinetic mixing.

Science Summaries: explaining LIGO-Virgo-KAGRA results to the global public
We compare two competing relativistic approaches to simulating the large-scale structure of the N-body universe. For this purpose, using appropriate alternative computer codes ("gevolution" and "screening"), we perform a series of cosmological simulations in boxes of different sizes and calculate the power spectra of the scalar perturbation Φ, the vector potential of the frame drag. the difference between the two scalar modes χ=Φ−Ψ.
Seach for supernova relic neutrinos at KamLAND
We demonstrate that the corresponding power spectra agree very well between the compared schemes. Since the perturbed Einstein equations have much simpler form in the "screening" approach, the simulation with this code consumes less computational time, saving almost 40% of CPU hours.
Search for unmodeled long duration gravitational waves for Ad- vanced LIGO and Advanced Virgo’s third observing run
We also improve on the upper probability limit of 8B solar neutrinos converting into antineutrinos via the Resonant Spin flavor precession with the neutrino magnetic moment. Moreover, we can set limits on the annihilation cross section for light dark matter pairs to neutrino pairs.
Search for Black Hole Merger Families
A resulting framework for these dynamical interactions is the so-called hierarchical triple merger scenario, which occurs when three black holes become gravitationally bound, causing two consecutive black hole mergers to occur. We perform our analysis for different upper limits on the mass distribution of first-generation BHs.
Search for Dark Matter with the PICO-500 Experiment
In such successive mergers, the black holes involved are directly related to each other, and thus this channel can be tested directly from the properties of the detected binary black hole mergers. Our results demonstrate the importance of the mass distributions' properties in constraining the hierarchical merger scenario.
Search for dark matter annihilation signals from unidentified Fermi- LAT objects with H.E.S.S
Since no significant very high-energy gamma-ray emission is detected in any of the four UFO datasets or the combined one, we derive constraints on the velocity-weighted annihilation cross-section product from the J factor for dark matter models. We derive 95% CL upper limits on J in the W+W-andτ+τ-annihilation channels for TeV dark matter particles.
Search for dark matter signals toward the irregular dwarf galaxy WLM with H.E.S.S
Given dark matter masses above a few hundred GeV, the observed UFOs could be identified as dark matter subhaloes, given their hard gamma-ray spectra in the few-ten-to-hundred GeV energy range. Assuming model-dependent predictions from cosmological N -body simulations of the J -factor distribution for Milky Way-sized galaxies, the dark matter models with masses greater than 0.3 TeV for the UFO emissions can be ruled out at high confidence.
