摘要

我们研究了狄拉克和克莱因-戈登方程，以及海沃德黑洞(BH)时空的灰体辐射。我们首先考虑使用纽曼-彭罗斯(NP)形式的零四分体的狄拉克方程。然后将方程分为角向部分和径向部分。从径向部分得到了一对具有有效势的一维Schrödinger类波动方程。为了检查势的行为，它们被绘制成相对于径向距离。此外，克莱因-戈登方程在海沃德黑洞时空中被考虑。最后，我们计算了玻色子和费米子的灰体因子，并对结果进行了图解和讨论。

The Dirac and Klein-Gordan equations and Greybody Radiation for the Regular Hayward Black Hole

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.
