摘要

为弯曲时空的规量场和费米子导出了 LSZ 型还原公式。公式的推导使用了也适用于平坦时空的守恒电流法。该方法可推广到更一般的量子场论。然后将公式应用于一些问题，以说明其用途。

Practical Derivations of Fermion and Gauge Boson Reduction Formulae in Curved Spacetimes

LSZ-type reduction formulae are derived for gauge fields and fermions in curved spacetime. The formulae are derived using a conserved current method applicable also to flat spacetimes. The method generalizes to more general quantum field theories. The formulae are then applied to a few problems to illustrate their use.
