introduction
  • Glashow-Weinberg-Salam model
  • W-boson mass causes some trouble
  • Goldston boson
  • Higgs mechanism

 

 

recipe

 

 

 

weak interactions
  • massive gauge bosons 
    • W and Z bosons

 

 

consequences
  • neutral currents
  • new mesons
  • parity violating effects
  • W and Z bosons

 

 

W-boson
  • massive charged spin 1

 

 

Z-boson
  • massive neutral spin 1 boson

 

 

weak force
  • neutron beta decay
  • muon decay
  • high-energy neutrino collisions with matter

 

 

three classes of weak interactions
  • leptonic reactions
  • semi-leptonic reactions
  • hadronic weak reactions

 

 

Higgs mechanism
  • Higges field
    • pervasive universal background field that modifies the simple electroweak gauge theory as the gravitational field caused by mass
  • two initial charged massless weak field W, W^{+}
    • mix with Higgs fields H^{+}, H^{-}
    • W fields get mass
  • two electrically neutral massless fields W^0, G^0
    • mix with neutral Higgs field H^0
    • Z-field massive neutral weak field
  • resulting bosons
    • W - massive charged spin 1
    • Z- massive neutral spin 1 boson
    • photon - massless spin 1
    • Higgs - massive neutral scalar spin 0
