Search for Stimulated Neutrino Conversion with an RF Cavity

Little is known on radiative decays of numu and nutau. Lifetimes can be constrained, or the process discovered, by a search for flavour conversion in a superconducting RF cavity installed in a neutrino beam. The lifetimes tested with such a method can be of interest for astrophysics and cosmology. In particular the conjecture which explains both the LSND and the SuperKamiokande signals by radiative decays of numu can be straightforwardly put to the test.
