1 Dec 2008 | Abstract: | We derive the two-loop effective action for covariantly constant field
strength of pure Yang-Mills theory in the presence of an infrared scale. The
computation is done in the framework of the worldline formalism, based on a
generalization procedure of constructing multiloop effective actions in terms
of the bosonic worldline path integral. The two-loop beta-function is correctly
reproduced. This is the first derivation in the worldline formulation, and
serves as a nontrivial check on the consistency of the multiloop generalization
procedure in the worldline formalism. | Source: | arXiv, 0812.0008 | Services: | Forum | Review | PDF | Favorites |
