论文摘要
我们研究了中微子重力从一个旋转的超质量黑洞中散射出来，该黑洞被带有逼真的磁场的薄积盘包围。中微子应该是具有非零磁矩的狄拉克颗粒。中微子沿任意轨迹移动，传入通量与赤道平面平行。我们准确地说明了重力和磁场对中微子运动及其自旋进化的影响。在准经典方法中证明，超层化中微子在任意重力场中的粒子散射中的螺旋性在粒子散射中是恒定的一般陈述。我们发现，在弯曲时空中外部场中中微子自旋进动考虑了外向中微子的可测量通量。对于系统的某些参数，这些通量被显着抑制。最后，我们讨论了观察我们银河系中核心超新星中微子的预测现象的可能性。
We study neutrinos gravitationally scattered off a rotating supermassive black hole which is surrounded by a thin accretion disk with a realistic magnetic field. Neutrinos are supposed to be Dirac particles having a nonzero magnetic moment. Neutrinos move along arbitrary trajectories, with the incoming flux being parallel to the equatorial plane. We exactly account for the influence of both gravity and the magnetic field on the neutrino motion and its spin evolution. The general statement that the helicity of an ultrarelativistic neutrino is constant in the particle scattering in an arbitrary gravitational field is proven within the quasiclassical approach. We find the measurable fluxes of outgoing neutrinos taking into account the neutrino spin precession in the external field in curved spacetime. These fluxes turn out to be significantly suppressed for some parameters of the system. Finally, we discuss the possibility to observe the predicted phenomena for core-collapsing supernova neutrinos in our Galaxy.
