Description
The Short-Baseline Near Detector (SBND) is a 112-ton Liquid Argon Time Projection Chamber (LArTPC) positioned 110 meters from the Booster Neutrino Beam (BNB) target at Fermilab. As the near detector of the Short-Baseline Neutrino (SBN) program, it is capable of recording around 3 million neutrino interactions per year. This enables precise measurements of unoscillated neutrino event rate and supports a rich analysis of neutrino-argon interactions. Electron neutrinos are of particular interest. Their showers are extremely challenging to reconstruct, and fewer models exist that accurately describe their interactions. Precise modelling of high energy $\nu_e$ interactions with pion producing final states, are particularly important in facilitating oscillation analyses. This poster introduces the SBND experiment and highlights the significance of neutrino event generator studies. It outlines the CC $1e1\pi^\pm 1p$ signal definition and presents an initial look into the key generator variables characterising this topology.
