Neutrino-nucleon cross-section model tuning in GENIE v3

We summarise the results of a study performed within GENIE global analysis framework, revisiting bare-nucleon cross-section tuning and, in particular, a) inclusive cross-section, b) low-multiplicity inelastic channels (single-pion and double-pion production), c) relative contributions resonance non-resonance processes to these final states. The same was with several different comprehensive model sets available Generator v3. In this work we careful investigation observed tensions between exclusive data, installed improvements handle systematics historic data. All tuned configurations discussed paper are through public releases Generator. With aim support consumers physics tunes by providing summaries our alternate constructions, relevant datasets their systematics, procedure results.
