For the trilepton channel, the background yield in the signal region is estimated using a control sample with the same crite- ria as for the signal, but requiring only two leptons

A search is presented for exotic decays of a Higgs boson into undetectable particles and one or two isolated photons in pp collisions at a center-of-mass energy of 8 TeV.. The

Event yields and background predictions based on simulated events for all three-lepton channels after the basic event selection, which includes the trigger, Z boson, third

Number of events with at least one track with the given number of low dE=dx measurements, for search data and the scaled Z-peak control sample background estimate.. The

The multijet background contribution is estimated using a control sample of events containing two (three) loose lepton candidates for the same-charge dilepton (trilepton)
