Evidence of Lensing of the Cosmic Microwave Background by Dark Matter Halos
... With this Letter, we demonstrate that CMB observations are now achieving the sensitivity and resolution to provide mass estimates of dark matter halos belonging to galaxy groups and clusters. With the ...

Gravitino dark matter and neutrino masses in partial split supersymmetry
... Because R-parity is not conserved, the lightest super- symmetric particle (LSP) will be unstable and decay into standard-model particles. This will occur very fast if the LSP is the traditional neutralino, losing it as a ...
