Abstract

Neutrinos are the most mysterious and interesting among all elementary particles. It does not have charge and it is massless according to S.M. Recent experiments indicate that neutrinos can oscillate from one avor to another avor which indicates the fact that neutrinos have tiny mass. The determination of mixing parameter and mass of neutrino is an interesting question in high energy physics. Furthermore, neutrinos could also be related to the matter-antimatter asymmetry of the universe, understanding of which requires determination of CP violation in neutrino sector. In this project, I have discussed about CP violation in neutrino oscillation in 3+1 scheme and compared it with ordinary three avour oscillation. The difference between oscillation probabilities of neutrinos and anti-neutrinos leads to CP violation. I investigated CP violation in neutrino sector in vacuum and matter using 1. three ordinary neutrinos(Ve; Vp and Vr) and with 2. one sterile neutrino withthree ordinary neutrinos ( 3+1 scheme).
