FCNC production of same sign Top quark pairs at the LHC
F. Larios, F. Penunuri
Abstract
We study the possibility of same sign top quark pair production at the LHC (and the VLHC) as a direct probe of FCNC processes. Besides the SM neutral Z boson, two other neutral bosons are considered, a top-Higgs type scalar and a Z' boson that appear in Topcolor assisted Technicolor models. We find that the FCNC couplings tqV (q=u,c ; V=H,Z,Z') may produce an interesting signal of same sign top quark pairs that could be observed at the LHC (VLHC).
