Rare top quark decays in Alternative Left-Right Symmetric Models

Abstract

We evaluate the flavor changing neutral currents (FCNC) decay t → H0 + c in the context of Alternative Left‐Right symmetric Models (ALRM) with extra isosinglet heavy fermions; the FCNC decays may place at tree level and are only supressed by the mixing between ordinary top and charm quarks. We also comment on the decay process t → c + γ, which involves radiative corrections.
