【摘要】

In the Standard Model (SM) of particle physics neutrinos are massless. However, various oscillation experiments have confirmed that neutrino possesses non-zero mass and their flavors are significantly mixed 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 the origin of neutrino mass whereas symmetry based studies have been very successful to explain the mixing patters of neutrinos. 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 and an overview of generalized CP method. Finally, we shall talk the consequences of such symmetry considering next generation super-beam experiment, DUNE and its impact on neutrinoless double beta decay.

Newton Nath is currently working as a Post-docotoral Research Assistant in the  Theoretical Physics Division of Institute of High Energy Physics, Chinese Academy of Sciences, Beijing. His research interests are broadly in the area of high energy particle phenomenology, more precisely in Neutrino Physics. To understand some of the interesting facts about neutrinos, he  is currently focusing on the following phenomenological aspects of neutrino physics: Neutrino Oscillation Physics (mainly, long baseline experiments, impacts of new physics like, non-standard interactions ), flavor symmetry models which explain neutrino masses and mixing patterns and sterile neutrino phenomenology. He has obtained his Master degree in particle physics from University of Hyderabad, India. After that, he moved to Physical Research Laboratory, Ahmedabad, India to complete his doctorate in Neutrino Physics. From September 2017, he is working in the group of Prof. Zhi-zhong Xing IHEP, Beijing as a PDF scholar.
