First Muon-Neutrino Charged-Current Inclusive Differential Cross Section Measurement for MicroBooNE Run 1 Data

This note presents MicroBooNE’s first ν_µ charged-current (CC) inclusive measurement using 6 months of Run 1 data (~ 1.6 × 10²⁰ POT). The measurement is presented as a function of reconstructed muon kinematics, including a first assessment of systematic uncertainties. The signal topology for a ν_µCC inclusive measurement is the presence of a neutrino-induced muon track with or without other accompanying particles. It is therefore the most inclusive cross section measurement that can be made, and due to the very clear signal definition allows straight-forward comparisons to theory models and other experiments. Additionally, this analysis selection can be used for more exclusive-channel cross section measurements, and be used to further develop reconstruction and event selection techniques. The note also discusses the techniques developed to distinguish neutrino-induced from cosmic muons for a sample with full angular coverage.. DOE Contract: AC02-07CH11359.
