Two-loop beta functions of the Sine-Gordon model
Janos Balog, Arpad Hegedus
We recalculate the two-loop beta functions in the two-dimensional Sine-Gordon model in a two-parameter expansion around the asymptotically free point. Our results agree with those…

The Intrinsic Coupling in Integrable Quantum Field Theories
J. Balog, M. Niedermaier, F. Niedermayer +3
The intrinsic 4-point coupling, defined in terms of a truncated 4-point function at zero momentum, provides a well-established measure for the interaction strength of a QFT. We sho…
