Elevating Neutrino Precision: SBND's Near-Detector Constraints

The SBND (Short Baseline Near Detector) at Fermilab is the near detector within the SBN (Short

Baseline Neutrino) Program. Situated 110 meters from the Booster Neutrino Beam (BNB), SBND

utilizes a liquid argon time projection chamber (LArTPC) as part of the broader SBN aimed at

exploring sterile neutrinos and other Beyond Standard Model Physics. I will discuss the role of

SBND in constraining both flux and neutrino cross-section models in oscillation measurements.

This study adopts a comprehensive approach to characterize diverse neutrino interactions and their

final state topologies, and it aims to contribute further to refine models and calculate associated

uncertainties using SBND data. This research plays a critical role in elevating the precision of

neutrino scattering, mitigating uncertainties, and advancing our comprehension of fundamental

physics.
