NEUTRINO OSCILLATIONS AND FARADAY-EFFECT

In analogy with the classical Faraday effect for the electromagnetic w ave, a Faraday effect for massive neutrinos is found to be somewhat ge neric description of neutrino oscillations when neutrinos traverse a d ense medium with or without a magnetic field. It is found that the Far aday angle for solar neutrino problem as an illustration of the Farada y effect for a neutrino wave provides conceptually convenient parametr ization of the various oscillations scenarios.
