Geant4Reweight: a framework for evaluating and propagating hadronic interaction uncertainties in Geant4

Geant4Reweight is an open-source C++ framework that allows users to 1) weight tracks produced by the GEANT4 particle transport Monte Carlo simulation according hadron interaction cross section variations and 2) estimate uncertainties in models comparing simulation's predictions data. The ability as simulated crucial propagation of systematic related secondary hadronic interactions current upcoming neutrino oscillation experiments, including MicroBooNE, NOvA, DUNE, well test beam experiments such ProtoDUNE. We provide motivation for weighting context uncertainty propagation, a description GEANT4's technique, our technique fitting momentum range 0--10 GeV/c, which typical hadrons these experiments.
