Flavor Changing Neutral Current searches in the top quark sector

Flavor changing neutral current (FCNC) interactions in top quark are highly suppressed in the Standard Model. Therefore, any measurable branching ratio for top FCNC decays is an indication of new physics. In this paper, searches for FCNC interactions in top quark production and decay at the LHC by the ATLAS Collaboration and the CMS collaboration are presented. FCNC searches in t $\rightarrow$ qH, t $\rightarrow$ q$\gamma$ and t $\rightarrow$ qZ decays, and in top quark production in qg $\rightarrow$ t or q $\rightarrow$ tg are summarized. None of the searches yielded positive results and exclusion limits on branching ratios, coupling strengths and cross-sections are obtained.
