Abstract
A brief review of new results and perspectives in neutrino physics is presented. An emphasis on a search for CP violation in neutrino oscillations and a search for sterile neutrinos is given. Status of measurement of the direct neutrino mass measurement and searches for neutrinoless double beta decay are also discussed.
Highlights
The discovery of neutrino oscillations [1, 2] that require neutrinos to be massive provided the convincing evidence of the existence of physics beyond the Standard Model
On top of that the nature of neutrino (Dirac or Majorana particle) and the absolute mass scale are very open issues. In addition to these fundamental problems there are several experimental signals which might hint on the existence of sterile neutrinos. This brief review covers the recent progress in study of neutrino oscillations and measurements of the absolute scale of the neutrino mass
The discovery of neutrino oscillations opened a window to new physics that is being intensively studied
Summary
The discovery of neutrino oscillations [1, 2] that require neutrinos to be massive provided the convincing evidence of the existence of physics beyond the Standard Model. The neutrino mixing angles θ12, θ23 and squared-mass differences ∆m221 and |∆m232| were measured in experiments with solar, atmospheric, reactor and accelerator neutrinos. On top of that the nature of neutrino (Dirac or Majorana particle) and the absolute mass scale are very open issues. In addition to these fundamental problems there are several experimental signals which might hint on the existence of sterile neutrinos. This brief review covers the recent progress in study of neutrino oscillations and measurements of the absolute scale of the neutrino mass
