Abstract
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.
