Exclusive proton final-states and kinematic imbalance in differential neutrino cross sections with the MicroBooNE detector

Making high-precision measurements of neutrino oscillation parameters requires an unprecedented understanding of neutrino-nucleus scattering. In this work, we present the first charged current double-differential cross sections in kinematic imbalance variables using data sets from the MicroBooNE detector. These variables characterize the imbalance in the plane transverse to an incoming neutrino. Thus, these variables act as a direct probe of nuclear effects such as final state interactions, Fermi motion, and multi-nucleon processes. Our measurement allows us to constrain systematic uncertainties associated with neutrino oscillation results performed by near-future experiments of the Short Baseline Neutrino (SBN) program, as well as by future large-scale experiments like DUNE.
