Abstract
We consider neutrino oscillations in a medium in which scattering processes are blind to the neutrino flavour. We present an analytical derivation of the synchronised behaviour obtained in the limit where the average scatteri ng rate is much larger than the oscillation frequency. We also examine MSW transitions in these circumstances, and show that a sharpening of the trans ition can result. (C) 2001 Elsevier Science B.V. All rights reserved.
