Abstract
We analyze the effect of flavor violation on the rare decays of the top quark to a one-loop through the Bestest Little Higgs (BLH) model, for which we include a new mixing term. We calculate the processes t→q_i V and t→q_i h^0, where q_i=u, c are light quarks and V_i=Z, gamma, g, h^0, are Standard Model (SM) bosons. These processes are mediated by the heavy bosons W'^(+-), H^(+-), phi^(+-) and the heavy bottom of the BLH. We found that the branching ratios (Br) have a higher sensitivity than their peers in the EM except for the gluon. Our best results are Br(t→c Z)~10^(-5), Br(t→c gamma)~10^(-6) and Br(t→c h^0)~10^(-8), which provides hints of new physics.
