Neutrino helicity oscillations in astrophysical environments: A many-body approach
Yiheng Xu, Julien Froustey, George M. Fuller +2
Neutrino rest mass enables left-handed states to "flip" to right-handed states and vice versa. In-medium effects can enhance the probability for such spin-flip. We demonstrate that…
