中微子物理若干前沿问题研究

We study the CP violating effect in neutrino oscillation, study the impact of the Earth matter effect in the measurement of CP violating parameter in future precision measurement of neutrinos and try to find way to efficiently distinguish the true CP violating effect from the Earth matter effect; we study mechanism of neutrino mass generation such as the seesaw mechansim, study the predictions of models of neutrino mass generation and flavor symmetries of neutrino mixing on the CP violating parameter in neutrino mixing matrix; we study keV scale sterile neutrino warm dark matter and models of this type of dark matter candidate, study the ways to detect this type of dark matter candidate and the possible background in the detection of it, study the predictions of models of this warm dark matter candidate on other physical processes; we study ways to detect the cosmic background neutrinos in the universe and try to make development in finding a practically possible detection scheme of cosmic background neutrinos; we study the possible events of supernovae neutrinos in the observation of next generation neutrino detectors, study the impact of the possible measurement on our understanding of the oscillation of supernovae neutrinos.
