Search for Top Quark Flavour-changing Neutral-current Decays at 8 TeV

We present a search for top quark flavor-changing neutral-current (FCNC) decays by the CMS Experiment. The data correspond to an integrated luminosity of 19.5 fb$^{-1}$ collected in proton proton collisions at the LHC at a centre-of-mass energy $\sqrt{s}$ = 8 TeV.

Sumario:We present a search for top quark flavor-changing neutral-current (FCNC) decays by the CMS Experiment. The data correspond to an integrated luminosity of 19.5 fb$^{-1}$ collected in proton proton collisions at the LHC at a centre-of-mass energy $\sqrt{s}$ = 8 TeV. The analysis uses background estimation techniques that are improved with respect to previous measurements. An upper limit for the branching fraction is determined.
