| Popis: | The searches for an underlying pattern in neutrino masses have motivated different proposals for textures in the neutrino mass matrix, which is also related to particular arranges of the mixing matrix. The current precise determinations of neutrino mixings have discarded some of the most studied proposals, such as the one involving a $\mu-\tau$ exchange symmetry. In this work, we investigate the relation of a still allowed $\mu-\tau$ reflection symmetry with the constraints of a magic pattern in the neutrino mass matrix. We show that both conditions cannot be fulfilled simultaneously in an exact but rather in an approximate way. Such considerations are used to restrict the values of CP-violating phases and some observables, like the neutrinoless double beta decay amplitude and the solar angle, that can be explored with forthcoming results.
