==introduction

  • This is not a quantum theory.
  • This can be regarded as a generalization of theory of electromagetisms., i.e. bundle + connections
  • looks like the coordinate invariance of gravity theory
  • Gauge theory
  • Usually, non-abelian gauge theory is called the YM theory.
    • QCD is one example.

 

 

==basic concepts

  • connection
  • curvature

 

 

==original Yang-Mills model

  • three kinds of photon
    • one ordinary photon
    • two electrically charged photons with spin 1 which is physically impossible to exist
  • massless gauge fields
    • for example, electromagnetic field(the only example at that time)

 

 

==weak force

 

 

 

==recipe

  • prepare Dirac fields
  • start with the free Dirac Lagrangian
  • we demand the Lagrangian to be invariant under the SU(N) local gauge transformations
  • structure constants are needed
  • self-interaction of gauge fields starts to appear

 

 

==Yang-Mills potential

  • dual role
    • a field in space-time
    • operator in the isotopic-spin space

 

 

==quantization of Yang-Mills theory

  • We want to quantize this theory.
  • standard model is a quantized version of a Yang-Mills theory of classical fields
