The short distance behavior of massive integrable quantum field theories is analyzed in terms of the form factor approach. We show that the on-shell dynamics is compatible with different definitions of the stress-energy tensor T(munu)(x) of the theory. In terms of form factors, this is equivalent to having a possible nonzero matrix element F1 of the trace of T(munu) on a one-particle state. Each choice of F1 induces a different scaling behavior of the massive theory in the ultraviolet limit.

Abstract

The short distance behavior of massive integrable quantum field theories is analyzed in terms of the form factor approach. We show that the on-shell dynamics is compatible with different definitions of the stress-energy tensor T(munu)(x) of the theory. In terms of form factors, this is equivalent to having a possible nonzero matrix element F1 of the trace of T(munu) on a one-particle state. Each choice of F1 induces a different scaling behavior of the massive theory in the ultraviolet limit.
