Neutrino Spin Transitions and the Violation of the Equivalence Principle
Mou Roy
Abstract
The violation of the equivalence principle (VEP) causing neutrino oscillations is of current interest. We study here the possibility of not only flavor oscillation but spin flavor oscillation of ultra high energy ( 1 PeV) neutrinos emanating from AGN due to VEP and due to the presence of a large magnetic field ( 1 Tesla) in AGN. In particular we look at the resonance spin flavor conversion driven by the AGN potential. Interesting bounds on the transition magnetic moment of neutrinos may therefore be obtained.
