Particular textures of the minimal seesaw model

Abstract

Following the Occam's razor principle, we explore the particular textures (featuring texture zeros and equalities) of the Dirac neutrino mass matrix in the minimal seesaw model (where only two right-handed neutrinos $N_1^{}$ and $N_2^{}$ are responsible for the generation of the light neutrino masses), in light of current neutrino experimental results and leptogenesis. The study will be performed for two particular patterns of the Majorana mass matrix $M_{\mathrm{R}}^{}$ for $N_1^{}$ and $N_2^{}$: (A) $M_{\mathrm{R}}^{}$ being diagonal $\left(\begin{array}{cc}{M}_1^{}& 0\\ 0& M_2^{}\end{array}\right)$; (B) $M_{\mathrm{R}}^{}$ being of the form $\left(\begin{array}{cc}0& M\\ M& 0\end{array}\right)$.
