f2 dominance of the energy-momentum tensor
Description
By assuming f2 dominance of the energy-momentum tensor and by using the Ward identity for the vertex function of the trace of the energy-momentum tensor and the two electromagnetic currents, the partial decay width of f2→γγ is estimated to be 1.9±0.2 keV, which is in a good agreement with the latest experimental data of 2.27±0.47 (stat.)±0.11(syst.) keV by the TOPAZ Collaboration in TRISTAN.
