The neutrino magnetic moment portal: cosmology, astrophysics, and direct detection
The neutrino magnetic moment portal: cosmology, astrophysics, and direct detection
We revisit the physics of neutrino magnetic moments, focusing in particular on the case where the right-handed, or sterile, neutrinos are heavier (up to several MeV) than the left-handed Standard Model neutrinos. The discussion is centered around the idea of detecting an upscattering event mediated by a transition magnetic moment …
