Inclusive Nucleon Emission Induced by Quasi--Elastic Neutrino--Nucleus Interactions

Abstract

We study the quasi--elastic contribution to the inclusive $({\nu }_l,{\nu }_{l}N)$, $({\nu }_l,l^{-}N)$, $({\bar{\nu }}_l,{\bar{\nu }}_{l}N)$ and $({\bar{\nu }}_l,l^{+}N)$ reactions in nuclei using a Monte Carlo simulation method to account for the rescattering of the outgoing nucleon. As input, we take the reaction probability from the microscopical many body framework developed in Phys. Rev. {\bf C70} (2004) 055503 for charged-current induced reactions, while for neutral currents we use results from a natural extension of the model described in that reference. The nucleon emission process studied here is a clear signal for neutral--current neutrino driven reactions, that can be used in the analysis of future neutrino experiments.
