TBA equations for excited states in the O(3) and O(4) nonlinear -model
J. Balog, A. Hegedus
TBA integral equations are proposed for 1-particle states in the sausage- and SS-models and their -model limits. Combined with the ground state TBA equations the exact mass gap…

Test of asymptotic freedom and scaling hypothesis in the 2d O(3) sigma model
J. Balog, P. Weisz
The 7--particle form factors of the fundamental spin field of the O(3) nonlinear --model are constructed. We calculate the corresponding contribution to the spin--spin correlati…

TBA equations for excited states in the Sine-Gordon model
J. Balog, A. Hegedus
We propose TBA integral equations for multiparticle soliton (fermion) states in the Sine-Gordon (massive Thirring) model. This is based on T-system and Y-system equations, which fo…
