μ and τ neutrino thermalization and production in supernovae: Processes and time scales
μ and τ neutrino thermalization and production in supernovae: Processes and time scales
We investigate the rates of production and thermalization of ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ and ${\ensuremath{\nu}}_{\ensuremath{\tau}}$ neutrinos at temperatures and densities relevant to core-collapse supernovae and protoneutron stars. Included are contributions from electron scattering, electron-positron annihilation, nucleon-nucleon bremsstrahlung, and nucleon scattering. For the scattering processes, in order to incorporate the full scattering kinematics at …
