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