Description
In the Standard Model of particle physics neutrinos are massless. However, various oscillation experiments have confirmed that neutrino possesses non-zero mass and provided hints to look for physics beyond the SM. On the other hand, theoretical origin of neutrino mass and their mixing is yet unknown. In literature, seesaw mechanism is considered as the simplest and elegant one to describe the theory behind neutrino mass. In this talk, we shall discuss \mu - \tau reflection symmetry which we embed into the minimal seesaw model so that both neutrino mass and mixing can be addressed. One immediate consequence of this symmetry is that it predicts \theta_23 = \pi/4 and \delta = \pm \pi/2 along with trivial Majorana phases which are well within current 3\sigma C.L. of global analysis. Furthermore, we shall talk the breaking of such symmetry considering renormalization group running as well as by introducing explicit breaking parameters at high energy neutrino mass matrices. Finally, we shall talk the consequences of such symmetry considering next generation super-beam experiment, DUNE.
