Electromagnetic Response Studies in the NOvA Test Beam

The NOvA Test Beam Program began data taking in 2019 with the purpose of improving the physics reach of the NOvA experiment. The Test Beam utilized a smaller NOvA detector using identical technology to that found in the NOvA experiment's near and far detectors, preceded by beamline instruments capable of providing precise measurements of particle momenta and species. This experimental setup was exposed to a 0.4 - 1.8 GeV /c beam of protons, kaons, pions, muons, and electrons (both charge signs). In this talk, I will discuss the Test Beam electron analyses, which measure electromagnetic response, efficiency, reconstruction, and modeling of electron interactions within the NOvA detector. These analyses are important because they will improve our knowledge of NOvA's systematic uncertainties for the electron neutrino appearance measurement. These measurements will help elucidate the neutrino mass ordering and constrain the parameter space for leptonic CP violation.
