利用黑洞外狄拉克场的一般协变方程，我们开发了大规模狄拉克场的散射理论。通过实现自由动力学的时间相关对数相移来抵消长程质量项，证明了无穷远处修正波算子的存在。由于正负能量波分量的存在，我们得到的相移是一个矩阵算子。
With a generally covariant equation of Dirac fields outside a black hole, we develop a scattering theory for massive Dirac fields. The existence of modified wave operators at infinity is shown by implementing a time-dependent logarithmic phase shift from the free dynamics to offset a long-range mass term. The phase shift we obtain is a matrix operator due to the existence of both positive and negative energy wave components.
