Abstract: The discovery that neutrinos can change flavor as they travel over long distances is one of the first indications of physics beyond the Standard Model. Long-baseline neutrino oscillation experiments, where detectors are placed far from the production point of the neutrinos, agree well with the three-flavor neutrino oscillation paradigm. However, some short-baseline experiments, where detectors are placed close to the production point of the neutrinos, show anomalous results. In particular, LSND and MiniBooNE observed excesses of electron neutrinos in muon neutrino beams which cannot be explained by three-flavor oscillations. These anomalies can be explained by the addition of new sterile neutrino flavors, but for this to be the correct explanation, long and short-baseline experiments must be consistent. If confirmed, the discovery of sterile neutrinos would be a paradigm shift in our understanding of neutrino properties and potentially of the evolution of the Universe. I will give an introduction to sterile neutrinos, present recent results from the MINOS and NOvA experiments, discuss new Deep Learning methods to improve sterile analyses, and describe prospects for the future.
