标题： A Probe Particle in Kerr-Newman-deSitter Cosmos

摘要： 我们研究了作用于一个自旋带电探测粒子（探针粒子）上的力，该粒子具有质量 \(m\) 和电荷 \(q\)，在缓慢旋转的Kerr-Newman-deSitter (KNdS) 黑洞（具有质量 \(M\) 和电荷 \(Q\)）中的情况。我们考虑探测粒子的自旋矢量与KNdS时空的角动量矢量平行的情形。我们考虑了KNdS时空在缓慢旋转极限下的引力自旋-自旋相互作用。当 \(Q = M\) 且 \(q = m\) 时，我们证明了包括自旋-自旋相互作用在内的力平衡成立，并且运动轨迹近似于deSitter时空中的粒子运动。这种力的抵消暗示了存在一个精确的旋转多KNdS黑洞解的可能性。 显示英文摘要

摘要： We consider the force acting on a spinning charged test particle (probe particle) with the mass m and the charge q in slow rotating the Kerr-Newman-deSitter(KNdS) black hole with the mass M and the charge Q. We consider the case which the spin vector of the probe particle is parallel to the angular momentum vector of the KNdS space-time. We take account of the gravitational spin-spin interaction under the slow rotating limit of the KNdS space-time. When Q=M and q=m, we show that the force balance holds including the spin-spin interaction and the motion is approximately same as that of a particle in the deSitter space-time. This force cancellation suggests the possibility of the existence of an exact solution of spinning multi-KNdS black hole.
