摘要

在描述黑洞附近高能宇宙射线的行为时，要考虑两个主要因素：强磁场和引力，后者决定了粒子的测地线运动。我们提请注意第三个因素：由于宇宙射线粒子具有非零自旋，自旋-重力耦合可以在超相对论态中发挥重要作用。考虑了自旋粒子对快速运动史瓦西质量场的重力磁分量的反应。给出了一些算例和数值估计。2025年由美国物理学会出版

Ultrarelativistic gravity and extremely energetic cosmic ray

Two main factors are taken into account when describing the behavior of energetic cosmic rays near black holes: the strong magnetic field and gravity, which determines the geodesic motion of the particles. We draw attention to the third factor: since cosmic ray particles have a nonzero spin, the spin-gravity coupling can play an important role in the ultrarelativistic regime. The reaction of the spinning particle on the gravitomagnetic components of the field of the fast-moving Schwarzschild mass is considered. Some examples and numerical estimations are presented.
