Castro-Alvaredo, O., Fring, A. & Korff, C. (2000). Form factors of the homogeneous sine-Gordon models. Physics Letters B, B484(1-2), 167-. doi: 10.1016/S0370-2693(00)00565-7

Abstract

We provide general determinant formulae for all n-particle form factors related to the trace of the energy momentum tensor and the analogue of the order and disorder operator in the $SU(3)_2$-homogeneous Sine-Gordon model. We employ the form factors related to the trace of the energy momentum tensor in the application of the c-theorem and find perfect agreement with the physical picture recently obtained by means of the thermodynamic Bethe ansatz. For finite resonance parameter we recover the expected WZNW-coset central charge and for infinite resonance parameter the theory decouples into two free fermions.
