First Measurement of Differential Cross Sections in Kinematic Imbalance Variables with Electron Neutrino Interactions Using the MicroBooNE Detector
Abstract
We report the first measurement of flux-integrated cross sections as a function of kinematic imbalance variables for electron neutrino interactions on argon. Kinematic imbalance variables, applied here to electron neutrino interactions for the first time, are particularly interesting due to their sensitivity to effects such as Fermi motion, multinucleon processes, and final-state interactions, providing a detailed lens to study neutrino-nucleus interactions. These measurements are performed using MicroBooNE's full dataset of 1.3 × 1021 protons on target from the Booster Neutrino Beam at the Fermi National Accelerator Laboratory. The measured cross sections are compared to several neutrino event generator configurations, revealing tensions between these models and data in the regions that are expected to be less dominated by final-state interactions.
