Reissner-Nordström时空上经典散射的软因子

Soft factors from classical scattering on the Reissner-Nordström spacetime

Karan Fernandes, Arpita Mitra

摘要:

本文研究了$4$维Reissner-Nordström时空中由带电荷和质量的点粒子在无束缚轨道上以渐近大速度运动时的探测散射引起的扰动。由此产生的经典辐射解是引力和电磁韧致辐射。我们使用这些经典的解决方案,以获得普遍的光子和引力子软因子的贡献,在树的水平上,它具有相同的形式,在文献中指出。软因子的表达式使我们能够调查的尾部贡献的记忆效应在晚时间的重力和电磁波形。我们发现,一般情况下,从电荷的贡献占主导地位,从质量在晚时间辐射。

英文摘要:

We consider perturbations of the $4$ dimensional Reissner-Nordström spacetime induced by the probe scattering of a point particle with charge and mass moving on an unbound trajectory with an asymptotically large velocity. The resulting classical radiative solutions are the gravitational and electromagnetic bremmstrahlung. We use these classical solutions to derive the universal photon and graviton soft factor contributions at the tree level, which have the same form as noted in the literature. The soft factor expressions enable us to investigate the tail contribution to the memory effect in late time gravitational and electromagnetic waveforms. We find that generically, the contribution from the charge dominates that from the mass in the late time radiation.
