摘要

考虑准拓扑引力中规则黑洞的无质量标量场扰动。在回顾了各种规则黑洞解的基础上，利用分波法计算了不同参数选择下的总吸收截面和部分吸收截面。结果表明，在准拓扑重力背景下引入的\(\alpha \)参数越大，总吸收截面越小。此外，我们发现时空维D对这组规则黑洞中无质量标量波的吸收和散射的影响不同于先前的计算。

Absorption and scattering of massless scalar waves by black holes in quasi-topological gravity

We consider massless scalar field perturbations of regular black holes in quasi-topological gravity. After reviewing various regular black hole solutions, we compute the total absorption cross-section and the partial absorption cross-section for different choices of the parameters using the partial wave method. The results show that the larger the parameter \(\alpha \), introduced in the context of quasi-topological gravity, the smaller the total absorption cross-section. In addition, we find that the influence of the space-time dimension D on the absorption and scattering of massless scalar waves in this set of regular black holes differs from earlier computations.
