摘  要:从有质量粒子的 Lagrangian 作用量出发,采用 Euler-Lagrange 变分原理在一般(非拖曳)坐标系下对五维Myers-Perry 黑洞中的类时和类光测地线方程作了自洽的、统一的推导,使得对转动黑洞隧穿辐射的研究不再局限于拖曳坐标系。紧接着采用 Parikh-Wilczek 的半经典隧穿方法,对有质量粒子在 Myers-Perry 黑洞视界附近的隧穿辐射重新做了研究,并给出了其隧穿几率。

Abstract: Starting from the Lagrangian action of mass particles, the Euler-Lagrange variational principle is used to make a self consistent and unified derivation to the time-like and light like geodesic equations in the five dimensional Myers-Perry black hole in the general (non towed) coordinate system, so that the research on the tunneling radiation of rotating black hole is no longer limited to the towed coordinate system. Then, using Parikh-Wilczek's semiclassical tunneling method, the tunneling radiation of mass particles near the field of view of Myers-Perry black hole is re studied, and its tunneling probability is given.

Keywords: Myers-Perry black hole; tunneling radiation; geodesic equation
