A Relation between the Anomalous Dimensions and OPE Coefficients in Asymptotic Free Field Theories
In asymptotic free field theories we show that part of the OPE of the trace
of the stress-energy tensor and an arbitrary composite field is determined by
the anomalous dimension of the composite field. We take examples from the
two-dimensional O(N) non-linear sigma model.Comment: 6 pages, plain TeX, uses harvma
