Descripción
Results are reported from a search for the top squark, the lighter of
the two supersymmetric partners of the top quark. The data sample
corresponds to 19.7 inverse femtobarns of proton-proton collisions at
sqrt(s) = 8 TeV collected with the CMS detector at the LHC. The search
targets top squark to b chi+/- and top squark to t(*) chi0 decay modes,
where chi+/- and chi0 are the lightest chargino and neutralino,
respectively. The reconstructed final state consists of jets, b jets,
missing transverse energy, and either one or two leptons. Leading
backgrounds are determined from data. No significant excess in data is
observed above the expectation from standard model processes. The
results exclude a region of the two-dimensional plane of possible top
squark and chi0 masses. The highest excluded top squark and chi0 masses
are about 700 GeV and 250 GeV, respectively.
