We present the first measurement of the single-differential νe þ ν¯e charged-current inclusive cross
sections on argon in electron or positron energy and in electron or positron scattering angle over the full
range. Data were collected using the MicroBooNE liquid argon time projection chamber located off axis
from the Fermilab neutrinos at the main injector beam over an exposure of 2.0 × 1020 protons on target. The
signal definition includes a 60 MeV threshold on the νe or ν¯e energy and a 120 MeV threshold on the
electron or positron energy. The measured total and differential cross sections are found to be in agreement
with the GENIE, NuWro, and GiBUU neutrino generators.
