Abstract

We consider the two-dimensional random bond q-state Potts model within the recently introduced exact framework of scale invariant scattering, exhibit the line of stable fixed points induced by disorder for arbitrarily large values of q, and examine the renormalization group pattern for q > 4, when the transition of the pure model is first order.
