Abstract

Neutrino physics is going through a very exciting phase. In last one and half years, crucial informations have been provided by both short and long baseline neutrino oscillation experiments. At short-baseline, recent neutrino oscillation studies seem to point towards the existence of active-sterile mixing. On the other hand at long-basline, recent T2K and MINOS data are in favor of non-zero theta13 opening up the possibility of observing CP-violation in the lepton sector. A stopped pion source provides neutrino beams with energy of a few tens of MeV from pion and muon decay-at-rest. A rich physics program can be accomplished with such a neutrino source. We discuss the role of such a neutrino facility to test short-baseline anomalies and to study CP violation in active neutrinos.
