Measurement of Nuclear Dependence in Inclusive Antineutrino Scattering with MINERvA*

MINERvA presents the current progress on its 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. 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.
