论文摘要
我们研究了带电的Ayón-Beato-García常规黑洞溶液的背景下无质量标量场的散射特性。使用数值方法,我们为散射角度和入射波频率的任意值计算差分散射横截面。我们将我们的结果与通过无质量颗粒的经典测地散射以及半经典荣耀近似获得的结果进行了比较,并表明它们在相应的限制中呈现出极好的一致性。我们还表明,对于黑洞电荷的低到中度值,对于散射角的任何值,Ayón-Beato-García和Reissner-Nordström黑洞溶液具有相似的散射特性,对于黑洞电荷的低到中度值。
We investigate the scattering properties of a massless scalar field in the background of a charged Ayón-Beato-García regular black hole solution. Using a numerical approach, we compute the differential scattering cross section for arbitrary values of the scattering angle and of the incident wave frequency. We compare our results with those obtained via the classical geodesic scattering of massless particles, as well as with the semiclassical glory approximation, and show that they present an excellent agreement in the corresponding limits. We also show that Ayón-Beato-García and Reissner-Nordström black hole solutions present similar scattering properties, for low-to-moderate values of the black hole electric charge, for any value of the scattering angle.
