Core collapse supernovae are, for all their spectacular visual display, neutrino events. Virtually all ( ~99%) of the 10^53 ergs of gravitational binding energy released in the formation of the nascent neutron star is carried away in the form of neutrinos of all six flavors. The current shock-reheating paradigm is wholly dependent on neutrinos produced inside the stalled shock imparting energy to the shock, thereby reviving it and moving it out in radius. We have performed a comparison of exact Boltzmann neutrino transport and an implementation of multigroup flux-limited diffusion(MGFLD) neutrino transport in a post-bounce core collapse supernova environment. Our analysis concentrates on those quantities central to the heating rate of the matter due to neutrino absorption, namely the luminosities, rms energies, and inverse flux factors of the electron neutrino and antineutrino radiation fields. Boltzmann transport yields inverse flux factors that are ~30% larger than MGFLD in the gain region. That difference translates to heating rates that are up to ~2-3 times larger for Boltzmann transport than for MGFLD. Additional details can be found at this URL.
