Sumario: | Searches for flavor changing neutral currents (FCNC) in top production and decay in CMS using data collected by
the Compact Muon Solenoid (CMS) experiment at $\sqrt{s}$ = 7 and 8 TeV
corresponding to an integrated luminosity of around 5 fb$^{-1}$ and 20 fb$^{-1}$
are presented. FCNC searches are conducted to probe $tqZ$, $tq\gamma$, $tqH$, and $tgq$ interactions in various channels.
There is no excess of signal observed over the data.
The upper limit of $\mathcal{B}(t \to u\gamma)$ $<$ 0.0161\%, $\mathcal{B}(t \to ug)$ $<$ 0.0355\%, $\mathcal{B}(t \to Zq)$ $<$ 0.05\% and
$\mathcal{B}(t \to cH)$ $<$ 0.56\% at 95\% confidence level are obtained.
Future prospects of FCNC searches with the upgraded detector at 14 TeV are also presented. |
