Abstract

We study possible smooth deformations of the generalized free conformal field theory in arbitrary dimensions by exploiting the singularity structure of the conformal blocks dictated by the null states. We derive in this way, at the first nontrivial order in the ε expansion, the anomalous dimensions of an infinite class of scalar local operators, without using the equations of motion. In the cases where other computational methods apply, the results agree.

(Received 13 December 2016; revised manuscript received 10 January 2017; published 9 February 2017) Our work has been strongly inspired by some unpublished notes of Yu Nakayama on smooth deformations of the free-field theory in d = 6 − ε dimensions.
