Description
We present the implementation of the Martini–Ericson–Chanfray–Marteau RPA-based (anti)neutrino cross section model in the GENIE neutrino event generator. The implementation includes both the quasielastic (1p1h) and multinucleon (npnh) interaction channels. The presentation will begin with an overview of the theoretical foundations of the model. Validation steps are then discussed, along with comparisons to other models currently available in GENIE. We then show predictions for cross sections on $^{12}$C, $^{16}$O, and $^{40}$Ar, and compare them with relevant experimental data. In particular, we highlight comparisons with the T2K simultaneous measurement of the muon neutrino charged-current cross section on oxygen and carbon without pions in the final state, and with the MicroBooNE multi-differential cross section measurements of $\nu_{\mu}$ - argon quasielastic-like interactions.
