论文摘要
我们为海沃德黑洞（BH）时空研究了狄拉克和克莱恩 - 戈登方程以及灰体辐射。我们首先使用Newman-Penrose（NP）形式主义中的零四位来考虑Dirac方程。然后将方程分为角部分和径向部分。从径向部分获得了一对具有有效电势的一维schrödinger像波动方程。为了检查电势的行为，它们在径向距离方面被绘制。此外，在海沃德BH时空中考虑了klein-gordon方程。最后，我们计算玻色子和费米子的灰体因素，我们的结果以图形方式显示并讨论。
We investigate the Dirac and Klein-Gordon equations, as well as greybody radiation, for the Hayward black hole (BH) spacetime. We first consider the Dirac equation using a null tetrad in the Newman- Penrose (NP) formalism. The equations are then separated into angular and radial parts. A pair of one-dimensional Schrödinger like wave equations with effective potentials is obtained from the radial part. In order to examine the behavior of potentials, they are plotted with respect to radial distances. Additionally, the Klein-Gordon equation is considered in the Hayward BH spacetime. At the end, we compute greybody factors for bosons and fermions and our results are shown graphically and discussed.
