Abstract
We study the possibility of production of same sign top quark pairs at the LHC as a direct probe of flavor changing neutral current (FCNC) processes in the tqg vertices. In particular, the LHC potential to probe the flavor violating parameter κ/Λ is investigated with 5, 10, 15, and 20 fb−1 of integrated luminosity of data of 7 and 8 TeV collisions. We find that the LHC can probe it down to 0.13 TeV−1 via double top production process. Also, we examine the effects of variation of factorization scale and different parton distribution functions on the total cross section of same sign top quark pair at the LHC. The results could be a valid starting point for a more detailed experimental study.
