We compute the form factors of the relevant scaling operators in a class of integrable models without internal symmetries by exploiting their cluster properties. Their identification is established by computing the corresponding anomalous dimensions by means of the Delfino-Simonetti-Cardy sum rule and further confirmed it by comparing some universal ratios of the nearby non-integrable quantum field theories with their independent numerical determination.

Abstract
We compute the form factors of the relevant scaling operators in a class of integrable models without internal symmetries by exploiting their cluster properties. Their identification is established by computing the corresponding anomalous dimensions by means of the Delfino-Simonetti-Cardy sum rule and further confirmed it by comparing some universal ratios of the nearby non-integrable quantum field theories with their independent numerical determination.File in questo prodotto:
