论文摘要
我们研究了对重力粒子间电位的自旋和速度依赖性贡献。此处采用的方法基于编码量子校正的形式因素的扩展。将自己限制在重力传播器的水平上，我们根据一般形式的形式来计算与spin-0和-1/2颗粒散射相关的非偏好性重力电位。我们讨论了有关不同类型的散射颗粒的比较方面，并且还与电磁电位的情况建立了一些比较。此外，我们将结果应用于基于非扰动方法的量子重力方法的明确示例。最后，在单杆单位部门以外的术语的存在下分析了牛顿奇异性的取消。
We investigate spin- and velocity-dependent contributions to the gravitational inter-particle potential. The methodology adopted here is based on the expansion of the effective action in terms of form factors encoding quantum corrections. Restricting ourselves to corrections up to the level of the graviton propagator, we compute, in terms of general form factors, the non-relativistic gravitational potential associated with the scattering of spin-0 and -1/2 particles. We discuss comparative aspects concerning different types of scattered particles and we also establish some comparisons with the case of electromagnetic potentials. Moreover, we apply our results to explicit examples of form factors based on non-perturbative approaches for quantum gravity. Finally, the cancellation of Newtonian singularity is analysed in the presence of terms beyond the monopole-monopole sector.
