A question about T-matrix in two-body scattering
Reply to thread
Message
[QUOTE="DrDu, post: 6523917, member: 210532"] The T-matrix, whose precise definition must be given somewhere else in the book, can be expanded into a power series in the coupling strength g. The zeroth- order term is trivial, as it corresponds to no scattering at all. The term containing the lowest non-vanishing power of g (g^1 in this example) is the leading order. The diagrams in fig. 2.3 are so called Feynman-diagrams and there are rules how they are in a one to one correspondence with actual terms in the perturbation series. [/QUOTE]
