标题： Acceleration of particles by black hole with gravitomagnetic charge immersed in magnetic field

摘要： 在弱磁化非旋转黑洞事件视界附近的测试带电粒子的碰撞已被研究。 外部磁场的存在会减小带电粒子的最内稳定圆轨道（ISCO）半径。 当存在非零的引力磁荷时，会发生相反的机制。 对于在ISCO上运动的带电粒子与从无限远处下落的中性粒子的碰撞，在存在外部渐近均匀磁场的情况下，引力磁荷可能会降低最大碰撞能量。 显示英文摘要

摘要： The collision of test charged particles in the vicinity of an event horizon of a weakly magnetized non-rotating black hole with gravitomagnetic charge has been studied. The presence of the external magnetic field decreases the innermost stable circular orbits (ISCO) radii of charged particles. The opposite mechanism occurs when there is nonvanishing gravitomagnetic charge. For a collision of charged particle moving at ISCO and the neutral particle falling from infinity the maximal collision energy can be decreased by gravitomagnetic charge in the presence of external asymptotically uniform magnetic field.
