| Abstract: | Canonical behavior of strong interactions at short distances causes an anomaly in the trace identity involving two electromagnetic currents and the energy-momentum tensor. The anomaly is connected with the high energy behavior of e+e− → γ → hadrons and the ?(700)γγ coupling constant. |
