Abstract (data abstract)
CERN-LHC. A search for physics beyond the standard model in events with at least three leptons is presented. The data sample, corresponding to an integrated luminosity of 19.5 inverse femtobarns of proton-proton collisions with center-of-mass energy sqrt(s) = 8 TeV, was collected by the CMS experiment at the LHC during 2012. The data are divided into exclusive categories based on the number of leptons and their flavor, the presence or absence of an opposite-sign, same-flavor lepton pair (OSSF), the invariant mass of the OSSF pair, the presence or absence of a tagged bottom-quark jet, the number of identified hadronically decaying tau leptons, and the magnitude of the missing transverse energy and of the scalar sum of jet transverse momenta. We also place a 95% confidence level upper limit of 1.3% on the branching fraction for the decay of a top quark to a charm quark and a Higgs boson (TOP --> CHARM HIGGS), which translates to a bound on the left- and right-handed top-charm flavor-violating Higgs Yukawa couplings, LAMBDA(HIGGS TOP CHARM) and LAMBDA(HIGGS CHARM TOP) respectively, of SQRT(ABS(LAMBDA(HIGGS TOP CHARM))**2 + ABS(LAMBDA(HIGGS CHARM TOP))**2) < 0.21. We also present the product of the acceptance and efficiency for the calculations of the 95% C.L. in several different SUSY scenarios.
