Search for top quark decays via Higgs-boson-mediated flavor-changing neutral currents in pp collisions at sqrt(s) = 8 TeV

Understand

A search is performed for Higgs-boson-mediated flavor-changing neutral currents in the decays of top quarks.

• The search is based on proton-proton collision data corresponding to an integrated luminosity of 19.7 inverse femtobarns at a center-of-mass energy of 8 TeV collected with the CMS detector at the LHC.
• Events in which a top quark pair is produced with one top quark decaying into a charm or up quark and a Higgs boson (H), and the other top quark decaying into a bottom quark and a W boson are selected.
• The Higgs boson in these events is assumed to subsequently decay into either dibosons or difermions.
