Muon-neutrino-induced charged current cross section without pions: Theoretical analysis

arXiv:1712.07134 · doi:10.1103/PhysRevC.97.045501

Abstract

We calculate the charged current cross sections obtained at the T2K near detector for -induced events without pions in the final state. The method used is quantum-kinetic transport theory. Results are shown first, as a benchmark, for electron inclusive cross sections on C and O to be followed with a detailed comparison with the data measured by the T2K collaboration on CH and HO targets. The contribution of 2p2h processes is found to be relevant mostly for backwards angles; their theoretical uncertainties are within the experimental uncertainties. Particular emphasis is then put on a discussion of events in which pions are first created, but then reabsorbed. Their contribution is found to be essential at forward angles.
