Particle Physics at the Fermilab Short-Baseline Neutrino Program
David Schmitz, University of Chicago
The Short-Baseline Neutrino (SBN) program consists of two liquid argon time projection chamber (LArTPC) neutrino detectors positioned along the axis of the Booster Neutrino Beam at Fermilab. The SBN far detector, ICARUS, began operation in 2022 and in November 2024 released its first physics result, a search for new physics. In December, the SBN near detector, SBND, also began collecting physics-quality neutrino beam data, thus officially marking the start of the full program. Two and a half months into a three-year run, SBND already has the largest neutrino-argon event sample in the world. With its unique combination of measurement resolution and statistics, SBND will carry out a rich program of neutrino-nucleus interaction measurements and novel searches for physics beyond the Standard Model (BSM). Using both detectors, SBN has unprecedented sensitivity to short-baseline neutrino oscillations and the possibility of the existence of a light sterile neutrino. In this talk, we will tell the story of the SBN program, share highlights from the on-going operations phase, and preview the physics results that are on the horizon.
