Does anyone know any books, websites, lecture notes etc that discuss on the poles of the S matrix being physically, the bound states?
The S-matrix, or scattering matrix, is a mathematical concept used in quantum mechanics to describe the behavior of particles during a scattering process. It relates the initial and final states of particles, and can be used to calculate the probability of a given scattering event.
Some recommended books on S-matrix theory include "The S-Matrix in Quantum Field Theory" by Laurent Baulieu, "The S-Matrix Theory of Strong Interactions" by Geoffrey Chew, and "S-Matrix Theory of Strong Interactions" by A. A. Sokolov and I. M. Ternov.
Yes, there are many websites and lecture notes available for learning about S-matrix theory. Some popular resources include the MIT OpenCourseWare lecture notes on "The S-Matrix in Quantum Field Theory" and the arXiv preprint archives for research papers on the topic.
Yes, the S-matrix theory is a universal concept that can be applied to all types of particles, including bosons and fermions. It is a fundamental tool in understanding the behavior of particles in the quantum world.
The S-matrix is closely related to other concepts in physics, such as quantum field theory and perturbation theory. It is also used in various areas of theoretical physics, including particle physics, nuclear physics, and condensed matter physics.
