Abstract
Sterile neutrinos are a new type of neutrinos, which do not interact with
matter via standard model interactions, and could explain the LSND
experiment (a 3.8sigma excess of events) and the MiniBooNE experiment (a 3sigma excess of
low energy events) anomalies. Recently, several new anomalies have started
to appear from other areas of physics suggesting that the sterile neutrino
hypothesis might be more than an exotic theory. The MicroBooNE experiment,
that just completed detector construction, will be dedicated to study directly the
MiniBooNE anomaly. This 170t Liquid Argon (LAr) detector will also
demonstrate the vast potential of this novel technology of neutrino
detection for future very large-scale neutrino experiments. I will present
the MicroBooNE experiment and describe how this new detector will address
the MiniBooNE excess. If MicroBooNE will answer the MiniBooNE excess, it
will not be able to cover the whole region allowed by the other experimental
anomalies observed. A new experiment using multiple LAr detectors located at
Fermilab in the US has been proposed to answer in a definitive way the
question of sterile neutrinos. I will describe the proposal and show how
this unique setup would provide a definitive answer to this now long lasting
question of sterile neutrino.
