Final state interaction effects in neutrino-nucleus quasielastic scattering

Abstract

We consider the charged-current quasielastic scattering of muon neutrinos on an Oxygen 16 target, described within a relativistic shell model and, for comparison, the relativistic Fermi gas. Final state interactions are described in the distorted wave impulse approximation, using both a relativistic mean field potential and a relativistic optical potential, with and without imaginary part. We present results for inclusive cross sections at fixed neutrino energies in the range $E_{\nu }=$ 200 MeV - 1 GeV, showing that final state interaction effects can remain sizable even at large energies.
