Description

We study the possibility of leptogenesis within the Alternative Left Right Model (ALRM). ALRM is a variant of the Left Right Symmetric Model. Unlike the usual Left Right Symmetric Model, it avoids the flavour changing neutral current. Type-I seesaw generates the majorana mass of the heavy RH neutrino ($\nu_R$), which gives the lepton number violating decay. We find that even for a large value of the yukawa coupling, there is a possibility of leptogenesis within the ALRM below the Davidson Ibarara bound.
