"Renormalization"의 두 판 사이의 차이

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

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
dimensional regularization
- regularization scheme in QCD
- regard the dimension as
