The S-matrix (scattering matrix) relates the initial state and the final state of a physical system undergoing a scattering process in quantum mechanics and quantum field theory. It is the unitary matrix connecting asymptotic particle states in the Hilbert space of physical states (scattering channels).

Sign of residues of S-matrix elements for bound states
I am currently studying S-matrices in 2D QFT and came across a statement I do not fully understand.
If one parametrizes 2-particle S-matrix elements with relative rapidity $\theta$, crossing-symmetry …
