Field Correlators in the Georgi-Glashow Model and Several Aspects of its String Representation
Abstract
String representations of the Wilson loop and of the non-Abelian analog of the 't Hooft loop, defined on the string world-sheet, are studied in the Londons' limit of the 4D Georgi-Glashow model. In the first case, massive gauge bosons yield only perimeter type terms, whereas in the second case, they also interact with the string, which enables one to derive the coefficient functions parametrizing the bilocal correlator of the dual field strength tensors. The asymptotic behaviours of these functions at small and large distances are argued to be in a good agreement with the observable lattice data.
