Form factors of solitoncreating operators in the sineGordon model
Abstract
We propose explicit expressions for the form factors, including their normalization constants, of topologically charged (or solitoncreating) operators in the sineGordon model. The normalization constants, which constitute the main content of our proposal, allow one to find exact relations between the short and longdistance asymptotics of the correlation functions. We make predictions concerning asymptotics of fermion correlation functions in the massive Thirring model, SU(2)Thirring model with anisotropy, and in the halffilled Hubbard chain.
