Abstract
We compute and also compare the contributions of canonical and non-canonical mass terms towards baryon asymmetry by considering type-II seesaw mass models of neutrinos: degenerate (3 varieties), normal hierarchical and inverted hierarchical (2 varieties). We have shown that for particular choices of parameter 'γ' (the so-called discriminator) for different neutrino mass models, the baryon asymmetry is largely dominated by canonical term. Within such type-II seesaw scenario, we find normal hierarchical (NHT3) mass model as the most favourable choice of nature.
