Abstract

We consider the branching ratio for the process t → c γ in the context of the General Two Higgs Doublet Model type III. We find that taking into account reasonable values for the parameter tan β is possible to get values of this branching ratio up to orders of magnitude lying in the range of sensitivity of near future top quark experiments. For values of B(t → c γ) ∼ 1-9 × 10^-5, values between 8-15 for tan β are allowed.
