Lower bound for the ratio of charged wino tracks to charged lepton tracks at LHC    [PDF]

Giorgio Calucci, Roberto Iengo

We infer lower bounds on signals of wino dark matter at LHC from the possible measure of tracks of seemingly unpaired charged leptons, members of a pair made of a charged and an unobserved neutral lepton, coming from a virtual W-vector-boson. We do that by working out the consequences of substituting the lepton pair with a wino pair, leaving untouched everything else of the proton-proton interaction at LHC, our key ingredient being just kinematics.
