Neutrino and antineutrino charged-current multi-nucleon cross sections
revisited
In this work we improve on several aspects of the computation of the (anti-)neutrino charged-current multi-nucleon cross section carried out in Phys.Rev.C 83 (2011) 045501 and Phys.Rev.C 102 (2020) 024601. Most importantly, we implement a consistent treatment of the nucleon self-energy in the $W^\pm N\to N'\pi$ amplitude entering the definition …
