Neutrino Oscillations in Dark Matter

Understand

We study neutrino oscillations in a medium of dark matter which generalizes the standard matter effect.

• A general formula is derived to describe the effect of various mediums and their mediators to neutrinos.
• Neutrinos and anti-neutrinos receive opposite contributions from asymmetric distribution of (dark) matter and anti-matter, and thus it could appear in precision measurement of neutrino or anti-neutrino oscillations.
• Furthermore, the standard neutrino oscillation can occur from the symmetric dark matter effect even for massless neutrinos.
