Neutrino signal from proto-neutron star evolution: Effects of opacities from charged-current-neutrino interactions and inverse neutron decay

NUCLEAR REACTIONS 1H(ν-bar, e+)n, 1n(ν, e-)p, E<100 MeV; derived expressions for medium-dependent charged-current reactions in fully inelastic kinematics, including contribution from weak magnetism; implemented weak reaction rates in the supernova model; simulated core-collapse supernova explosions and proto-neutron star (PNS) deleptonization; analyzed subsequent neutrino signal depending on the treatment of weak interactions; investigated nuclear medium dependence at the mean-field level, with the inverse neutron decay as new opacity source; calculated complete nucleosynthesis outcome from core-collapse supernova explosion simulation.
