Progress towards a muon-neutrino induced charged-current single charged pion cross section measurement with at least one proton using transverse kinematic imbalance (TKI) variables in MicroBooNE

MicroBooNE is a short baseline neutrino experiment situated on the Booster Neutrino Beam (BNB) at Fermi National Accelerator Laboratory. Constructed primarily to investigate the MiniBooNE low energy excess, MicroBooNE also has a broad neutrino interaction cross section measurement program using over five years of recorded beam data. The MicroBooNE detector uses the Liquid Argon Time Projection Chamber (LArTPC) technology to produce mm-scale resolution images of neutrino interactions. Charged current single charged pion interactions, particularly those produced via resonance, will be one of the dominant topologies for DUNE. Taking advantage of the high resolution of our LArTPC images, we use a suite of custom 3D deep-learning tools to reconstruct this topology in MicroBooNE, measure transverse kinematic imbalance (TKI) variables to probe nuclear effects, and extract a cross section. This talk will present the status and results of this analysis.
