The <S-matrix> maps incoming asymptotic states to outgoing asymptotic states. Its connected transition matrix elements contain an overall energy-momentum <Dirac delta function> and an invariant <scattering amplitude>. In <quantum field theory>, the <LSZ reduction formula> obtains these elements from amputated field correlators.
