论文摘要
我们研究低能无质量和巨大的微小耦合标量磁场的散射，这是通过渐近平坦的可遍性虫洞的散射。我们为这一问题提供了全面的处理，该问题为相应有效电位的传播和反射幅度提供了分析表达式和虫洞的吸收横截面的幅度。我们的结果基于最近开发的时间独立散射理论的动态表述，适用于大量的虫洞空间，包括带有急剧过渡的虫洞，Ellis蠕虫孔及其概括。
We study the scattering of low-energy massless and massive minimally coupled scalar fields by an asymptotically flat traversable wormhole. We provide a comprehensive treatment of this problem offering analytic expressions for the transmission and reflection amplitudes of the corresponding effective potential and the absorption cross section of the wormhole. Our results, which are based on a recently developed dynamical formulation of time-independent scattering theory, apply to a large class of wormhole spacetimes including a wormhole with a sharp transition, the Ellis wormhole, and a family of its generalizations.
