Description

Leptonic CP violation is one of the most important topics in neutrino physics. CP violation in
the neutrino sector is also strongly related to the nature of the neutrino: whether it is a Dirac
or a Majorana particle. In this contribution CP-violating effects in Majorana neutrino
oscillations in supernova media are studied. We show that resonances in neutrino-
antineutrino oscillations induced by strong magnetic fields of astrophysical objects appear in
the case of nonzero CP-violating phases. Our findings suggest a potential astrophysical setup
for studying the nature of neutrino masses and leptonic CP violation and may be important
for future neutrino experiments, for example, such as JUNO and Hyper-Kamiokande.

Based on: A. Popov and A. Studenikin, “Manifestations of nonzero Majorana CP-violating
phases in oscillations of supernova neutrinos”, Phys. Rev. D 103 (2021) 11, 115027.
