当碰撞参数远大于光子波长时，偏转角的能量依赖性是一些量子引力理论中的常见预测。对于低能量光子，偏转角恢复到GR的预测，但对于无限能量光子，偏转角减小到零。在本文中，我们发展了一种有效的方法来计算光子的轨迹和其他偏转相关的量的半经典的通过使用包括量子引力的修正。这种方法可以为在外部引力场中传播的光子提供更多信息。我们用这种方法计算了微黑洞的视界，发现它们都与能量有关，并随着能量的增加而减小到零。
The energy dependence of the deflection angle is a common prediction in some quantum gravity theories when the impact parameters are much larger than the photon wavelength. For low energy photons, the deflection angle recovers to the prediction of GR, but it reduces to zero for infinite energy photons. In this paper, we develop an effective approach to calculate the trajectory of photons and other deflection-related quantities semiclassically by replacingwithto include the correction of quantum gravity. This approach could provide more information for photons traveling in an external gravitational field. We compute the horizon of a micro black hole with this method and find that they are all energy-dependent and decrease to zero as the energy increases to infinity.
