Findings

Neutrino oscillations provide constraints on the rotation parameter of black holes.

Magnetic field, temperature, and electron asymmetry influence neutrino oscillation effects.

The study offers insights into the physical conditions at the base of Pop III GRB ejecta.

Abstract

Population III stars are believed to be rapidly-rotating sources with a mass range of hundreds to thousand of solar masses. Masses larger than 260 M$_\odot$ are expected to collapse resulting in central rotating Kerr black holes with large rotation parameter a. Due to particle-antiparticle asymmetry is small, we use the neutrino effective potential up to order $1/M_W^4$ in a magnetized plasma at the base of the ejecta to constrain the rotation parameter by means of neutrino oscillations. Additionally, we investigate the implications in the magnetic field, temperature and electron asymmetry.
