Electroweak single-pion production off the nucleon: effective implementation in Monte Carlo event generators (part 2)

Neutrino-induced single-pion production (SPP) provides an important contribution to neutrino-nucleus interaction, ranging from intermediate to high energies. There exist a good number of low-energy models in the literature to describe this process in the region around the Delta resonance. However, their implementation in the Monte Carlo event generators, that are used in accelerator-based neutrino oscillation experiments, is still very limited. I will present a framework exhaustively described in Ref. [J.E. Sobczyk et al., Phys.Rev. D98 (2018) 073001] and its potential to be used for generic and optimized implementations of SPP models. The discussion will be exemplified using the model developed by the Ghent group [R. González-Jiménez et al., Phys.Rev. D95 (2017) 113007] and its implementation in NuWro Monte Carlo generator.
