Search For Supersymmetry In 8 Tev Proton-Proton Collision Events With Bottom-Quark Jets And Missing Transverse Energy
A search for supersymmetry in a sample of proton-proton collision events with a center-of-mass energy of 8 TeV is presented. The sample, collected with the Compact Muon Solenoid detector at the Large Hadron Collider, corresponds to an integrated luminosity of 19.4 fb[-]1 . Events are required to have large missing transverse energy, at least three jets, and at least one identified bottom-quark jet. Numbers of events in exclusive bins of the scalar sum of jet transverse momentum values, missing transverse energy, and bottom-quark jet multiplicity are found to be consistent with the standard model expectations. The results are interpreted as 95% confidence level upper limits on simplified supersymmetric models approximating gluino mediated bottom- and top-squark production.
