Rare top quark decays in Alternative Left-Right Symmetric Models

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...

Description
Summary: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 + gamma, which involves radiative corrections.
