Description

The non-zero value of the reactor mixing angle ${\theta }_{13}$ has ruled out the possibility of $\mu$-$\tau$ symmetry in neutrino mass matrix, there can still be a magic symmetry in neutrino mass matrix. In this context, we explore several classes of two texture zeros such as Class $A$, Class $B$, Class $C$ and Class $D$ in magic neutrino mass matrix and obtain the relation between one unknown phase $\varphi$ and two known parameters: $\mathrm{\Delta }{m}_{23}^2$ and ratio of two mass square difference (r=$\mathrm{\Delta }{m}_{12}^2$/$\mathrm{\Delta }{m}_{23}^2$). We also analyses the variation of unknown phase $\varphi$ with respect to mixing angles (${\theta }_{13}$ and ${\theta }_{23}$), Dirac CP violating phase $\delta$, Majorana phases ($\alpha$ and $\beta$) and Jarlskog invariant CP violation parameter J and their experimental validity.
