Introduction to Neutrino Physics and Leptogenesis.

      Аннотация: The Standard Model (SM) of particle physics, after discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 has become the most successful theory of elementary particles and their interactions except gravity. However, the SM by itself is not a complete picture of all the fundamental particles, as it can not explain many of their observed phenomena. Origin of tiny neutrino mass and matter-antimatter asymmetry are two of such phenomena which can be explained only within the framework of some beyond Standard Model (BSM) physics. In this book, we first try to focus on theoretical as well as the phenomenological studies of different neutrino mass models to constrain the absolute neutrino mass, neutrino mass hierarchy, Dirac and Majorana CP phases from the requirement of producing the correct neutrino oscillation data. After that, we further constrain these presently undetermined neutrino parameters from the observed baryon asymmetry of the Universe by assuming it to be created through the mechanism of leptogenesis.
