Study of ATLAS sensitivity to FCNC top decays

Mostrar otras versiones (1)

The ATLAS experiment sensitivity to Flavour Changing Neutral Currents top decays ($t\to qZ$, $t\to q\gamma$ and $t\to qg$) was studied. Different analyses, corresponding to the $t\bar t$ production at LHC and subsequent $t(\bar t) \to bW$ and $\bar t (t) \to qX$ ($X=Z,\gamma,g$) decays are presented...

description The ATLAS experiment sensitivity to Flavour Changing Neutral Currents top decays ($t\to qZ$, $t\to q\gamma$ and $t\to qg$) was studied. Different analyses, corresponding to the $t\bar t$ production at LHC and subsequent $t(\bar t) \to bW$ and $\bar t (t) \to qX$ ($X=Z,\gamma,g$) decays are presented. The branching ratio sensitivity (assuming a $5\sigma$ signal significance) and 95\% confidence level limits on the branching ratio (in the hypothesis of signal absence) were obtained.
