超新星中Majorana中微子的振荡与CP破坏

Oscillations of Majorana neutrinos in supernova and CP violation

Artem Popov, Alexander Studenikin

摘要:

轻子CP破坏是中微子物理研究的重要课题之一。中微子扇区中的CP破坏与中微子的性质密切相关:无论它们是狄拉克粒子还是马约拉纳粒子。在\cite{Popov:2021icg}中,我们证明了对于Majorana中微子,在超新星核坍缩过程中,非零Majorana CP-破坏相的中微子振荡与强磁场相结合,可以在中微子振荡中诱发新的共振,例如在$ν_e \to \barν_τ$通道中。本文进一步研究了Majorana中微子振荡中的新共振,特别是这些共振的振幅与能量的关系。我们的发现为研究中微子质量和轻子CP破坏的性质提供了一个潜在的天体物理学设置,并可能对未来的中微子实验,如JUNO,Hyper-Kamiokande和DUNE很重要。

英文摘要:

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 \cite{Popov:2021icg} we have shown that for Majorana neutrinos arance of nonzero Majorana CP-violating phases combined with strong magnetic field during supernova core-collaple can induce new resonances in neutrino oscillations, for example in $ν_e \to \barν_τ$ channel. In this contribution we further study new resonances in Majorana neutrino oscillations, in particular energy dependence of amplitudes of these resonances. 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.
