introduction
- transition amplitude are too hard to calculate from the theory, except in infinite time limits
- those limits are the entries of the S-matrix
- typical way to compute S-matrix entries is using correlation functions and Ward identity
probability amplitude
- probability amplitude from initial states to final states
- Feynman diagram is a tool to compute the probability amplitudes.
- transition amplitude
- scattering amplitude
- computation of S-matrix (S = Scattering)
- cross section
- these are important because they are physically measurable quantity
- similar to correlation functions in Conformal Field Theory
- look at correlation functions and Ward identity page
S-matrix
- functions of complex rapidity difference \theta
- unitarity
- crossing-symmetry
- rapidity in special relativity
exact S-matrices
bootstrap equations
- Path integral
- string S-matrix
- affine Toda field theory
- quantum sine-Gordon field theory
- Ising CFT
- Dorey's rule
