Query: The MSW effect in a fluctuating matter density   We consider the effect on matter-enhanced neutrino flavor transformation of a
randomly fluctuating, delta-correlated matter density. The fluctuations will
produce a distribution of neutrino survival probabilities. We find the mean and
variance of the distribution for the case of solar neutrinos, and discuss the
possibility of placing a limit on solar density fluctuations using neutrino
data.
