Search for flavor changing neutral current in top production and decays

초록

Searches for flavor changing neutral currents in top production and decay using data collected by the Compact Muon Solenoid (CMS) experiment at √s = 7 and 8 TeV are presented, corresponding to an integrated luminosity of around 5 fb-1 and 20 fb-1. FCNC searches are conducted to probe tqZ, tqy, tqH, and tgq interactions in various channels. By the time of the 38th ICHEP conference in 2016, the upper limits on B(t → uγ) < 0.013%, B(t → ug) < 0.036%, B(t → uZ) < 0.05% and B(t → uH) < 0.42% at the 95% confidence level had been obtained by the CMS collaboration.
