Electroweak theory

introduction

• Glashow-Weinberg-Salam model
  

• W-boson mass causes some trouble
  
• Goldston boson
  
• Higgs mechanism
  

 

 

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
