renormalization
- way of pulling out sensible answers from Feynman diagrams that explode
- there are two parts in the renormailization program
- regularization - the divergences must be written down in some way so that they can be compared, added and subtracted
- renormalization proper - the various divergences must be gathered together and extracted from the rest of the calculation
- regularization - the divergences must be written down in some way so that they can be compared, added and subtracted
regularization
- root of the problem
- probability of creating particles of colossal energies
- in terms of Feynman diagrams, the momentum in a loop can run away to infinity
- probability of creating particles of colossal energies
- dimensional regularization
- regularization scheme (especially good in QCD)
- regard the dimension as a continuous quantity
- coupling constant changes accordingly as the dimension changes continuously
- we get a new parameter called regularization scheme
- regularization scheme (especially good in QCD)
QED renormalization
- three basic divergent diagrams and three counter-terms to match and three infinite constants
- electron self-energy diagram transforms the bare electron mass into the physical ones
- vertex diagram links bare electri charge to phstical electric charge
- photon self energy is related to the transformation of bare electric field strngth to physical field strength
