Measurement of Nuclear Dependence in Inclusive Antineutrino Scattering with MINERvA

The MINERvA experiment was designed to perform precision studies of neutrino-nucleus scattering in the GeV regime on various nuclear targets using the high-intensity NuMI beam at Fermilab. This poster outlines the current progress on MINERvA's first inclusive charged-current analysis of antineutrino interactions on iron, lead, and water using antineutrino energy and Bjorken x. The interactions on carbon and hydrocarbon are also reported. The results use data produced in the NuMI beamline with antineutrino beam peak energy of approximately 6 GeV taken from 2016 to 2019. The measurements utilize events of energies 2 < E < 50 GeV. The event selection and the background prediction related to the complex structure of the target region and machine-learning reconstruction of the interaction vertex are presented. The importance of the Bjorken x variable to investigate nuclear modifications and the challenges of unfolding in x are discussed. The analysis will provide high-statistics, self-contained studies of nuclear effects and nuclear dependence, and comparisons to the current neutrino interaction generators such as GENIE.
