标题： Neutrino Spin Transitions and the Violation of the Equivalence Principle

摘要： 违反等效原理（VEP）导致中微子振荡目前引起了关注。 我们在这里研究了由于VEP以及活动星系核（AGN）中存在强磁场（$ \sim$1特斯拉）而导致的超高能（$ \sim$1 PeV）中微子从AGN发出时，不仅可能发生味振荡，还可能产生自旋味振荡的可能性。 特别是我们考察了由AGN势驱动的共振自旋味转换。 因此，可能会得到关于中微子跃迁磁矩的有趣限制。 显示英文摘要

摘要： 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 ($ \sim$ 1 PeV) neutrinos emanating from AGN due to VEP and due to the presence of a large magnetic field ($ \sim$ 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.
