Matter- and magnetically-driven flavor conversion of neutrinos in magnetorotational collapses

Irene Tamborra, Marco Manno, Pablo Mart\'inez-Mirav\'e

In magnetorotational stellar collapses, neutrinos with a small magnetic moment undergo resonant flavor-changing mixing with antineutrinos for Majorana particles.

Claims

C1strongest claim

For Majorana neutrinos, this leads to resonant flavor-changing neutrino-antineutrino mixing. The event rate expected from a Galactic collapse at current and next-generation neutrino telescopes, such as IceCube and Hyper-Kamiokande, strongly depends on the orientation of the magnetorotational collapse with respect to the observer direction and flavor conversion scenario.

C2weakest assumption

Neutrinos possess a non-zero magnetic moment at or below 10^{-12} μ_B and the 3D neutrino-MHD simulation accurately supplies the density and magnetic-field profiles needed for the resonant conversion calculations to hold.

C3one line summary

In magnetorotational stellar collapses, neutrinos undergo resonant flavor conversion in matter plus magnetic-moment-driven chirality flipping for Majorana neutrinos, producing orientation-dependent event rates at detectors that peak 400-600 ms after bounce.
