Analysis of events with b-jets and a pair of leptons of the same charge in pp collisions at root s = 8 TeV with the ATLAS detector
Abstrakt
An analysis is presented of events containing jets including at least one b-tagged jet, sizeable missing transverse momentum, and at least two leptons including a pair of the same electric charge, with the scalar sum of the jet and lepton transverse momenta being large. A data sample with an integrated luminosity of 20.3 fbMINUS SIGN 1 of pp collisions at root s = 8TeV recorded by the ATLAS detector at the Large Hadron Collider is used.
Standard Model processes rarely produce these final states, but there are several models of physics beyond the Standard Model that predict an enhanced rate of production of such events; the ones considered here are production of vector-like quarks, enhanced four top-quark production, pair production of chiral b0-quarks, and production of two positively charged top quarks.
