Title: Neutrino-nucleus interaction modeling in long-baseline neutrino experiments

Abstract: Neutrino-nucleus cross sections are an important facet of interpreting results in accelerator neutrino experiments. However, these cross sections are still not theoretically well understood, which can have consequences in a wide array of physics analyses. In this talk, I will discuss how the interplay between cross section mis-modeling and near detector tunes, widely adopted in accelerator neutrino experiments to address cross section uncertainties, affects new physics searches and precision SM oscillation analyses. I will first present an illustrative new physics scenario–light sterile neutrinos–present the relevant observable spectra before and after tune, and discuss the prospects of identifying new physics. I will then move to an examination of the cross-section dependence of the precision oscillation goals of the DUNE experiment.
