Description
In this talk I will analyze the Thermodynamic Bethe Ansatz (TBA) for various integrable S-matrices in the context of generalized TTbar deformations. I will show how a turning point in the TBA, interpreted as a Hagedorn temperature, arises from theories with more resonances than bound states. I will explain the numerical method which allows us to pass the turning point and discuss some properties of the unconventional UV behaviour. I will focus on theories with k resonances and — to our knowledge — a new family of UV complete integrable theories.
