Product Description
This work contains an estimation of the observability of the Flavour Changing Neutral Currents (FCNC) in top decays with the CMS experiment at the future Large Hadron Collider (LHC). Since expected branching ratios for top FCNC in the Standard Model are eagerly low, any experimental evidence for a top quark FCNC interaction would signal the existence of physics beyond the Standard Model. A wide variety of Standard Model processes have been considered into background, and selection is optimized in order to maximize the significance in the signal region. A full set of systematic effects, originating from detector or theoretical uncertainties, are added to the simulation and their impact on the analysis is established. Results are presented for several background levels and different experimental conditions, then extrapolated to the highest attainable LHC luminosities. An improvement of two orders of magnitude in sensitivity to FCNC branching ratio is obtained, allowing to shed light on different new physics scenarios. |
