Abstract: Short-baseline accelerator neutrino experiments sit at the intersection of several open questions in neutrino physics. Persistent anomalies at L/E ~ 1 m/MeV, most notably the LSND and MiniBooNE electron-flavor excesses, have motivated a dedicated experimental program to test the existence of light sterile neutrinos, while the same detectors provide high-statistics measurements of neutrino–argon interactions, sensitive searches for physics beyond the Standard Model, and a proving ground for liquid argon time projection chamber technology on the path to DUNE. This talk will review the current status of beam-based short-baseline experiments, including the Fermilab Short-Baseline Neutrino program (MicroBooNE, SBND, and ICARUS) and JSNS² at J-PARC. Highlights include MicroBooNE’s search for 3+1 sterile neutrino oscillations using two neutrino beams, as well as recent progress from SBND, ICARUS, and JSNS². Prospects for the coming years and the program’s role in preparing for the next generation of long-baseline experiments will also be discussed.
