Abstract
Leptonic CP violation is one of the most important topics in neutrino physics. CP violation in the neutrino sector is strongly related to the nature of neutrinos: whether they are Dirac or Majorana particles. In [1] we have shown that for Majorana neutrinos appearance of nonzero Majorana CP-violating phases combined with strong magnetic field during supernova core-collapse can induce new resonances in neutrino oscillations, for example in \({{\nu }_{{\text{e}}}} \to {{\bar {\nu }}_{\tau }}\) channel. In this paper we further study new resonances in Majorana neutrino oscillations, in particular energy dependence of amplitudes of resonant oscillations. 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, such as JUNO, Hyper-Kamiokande and DUNE.
