Weak magnetism for antineutrinos in supernovae
Weak magnetism for antineutrinos in supernovae
Weak magnetism increases antineutrino mean free paths in core collapse supernovae. The parity violating interference between axial vector and vector currents makes antineutrino-nucleon cross sections smaller than those for neutrinos. We calculate simple, exact correction factors to include recoil and weak magnetism in supernova simulations. Weak magnetism may significantly increase …
