论文摘要
我们考虑脱离鹰辐射对涉及量子场的黑洞的散射过程的影响。这里的重点是通过从四维Schwarzschild黑洞中交换虚拟鹰派引力来介导的标量场的重力散射的情况。我们的结果是在黑洞的世界有效场理论的背景下获得的,并且在半古典限制中有效,在Schwarzschild Radius $ R_S $大于Planck Length $ 1/m_ {pl} $的情况下。此外,我们假设四摩托姆交换$ q $小于$ r_s^{ - 1} $,并且传入的粒子的能量比黑洞的鹰温度大。我们获得的非弹性横截面是一种新的领先阶量子重力效应,在$ q^2/m_ {pl}^2 $中以相同的顺序产生,就像众所周知的一环吸尘器极化校正对大型颗粒之间的重力散射。
We consider the effects of off-shell Hawking radiation on scattering processes involving black holes coupled to quantum fields. The focus here is to the case of gravitational scattering of a scalar field mediated by the exchange of virtual Hawking gravitons from a four-dimensional Schwarzschild black hole. Our result is obtained in the context of a worldline effective field theory for the black hole, and is valid in the semi-classical limit where the Schwarzschild radius $r_s$ is larger than the Planck length $1/m_{Pl}$. In addition, we assume that four-momentum exchange $q$ is smaller than $r_s^{-1}$ and that the incoming particle has energy larger then the black hole's Hawking temperature. The inelastic cross section we obtain is a new, leading order quantum gravity effect, arising at the same order in $q^2/m_{Pl}^2$ as the well understood one-loop graviton vacuum polarization corrections to gravitational scattering between massive particles.
