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

 

 

S-matrix
  • functions of complex rapidity difference \theta
  • unitarity
  • crossing-symmetry
