The S-matrix is a fundamental tool in Quantum Field Theory used to compute scattering amplitudes for various processes. To effectively utilize the S-matrix, one must study comprehensive resources such as "An Introduction to Quantum Field Theory" by Peskin & Schroeder. Mastery of the S-matrix requires extensive coursework, as it encompasses complex theoretical concepts that cannot be fully addressed in brief forum discussions. For practical application, a solid understanding of field operators like ##\phi(x,t)## is essential.

That is more help than is within the scope of a PF thread. You are basically asking for a course in S matrix theory, and for that you need a textbook (such as the one @strangerep suggested), not a PF thread.gremory said:
Yes. However...gremory said:
It's certainly possible, but as above, learning how to do it takes one or more full-time courses in S-matrix theory. It's not something we're going to be able to teach you in a PF thread.gremory said:
