| Abstract: | The EVDM and factorization technique are extended to the case of two tagged photons. The results obtained from both methods are remarkably close, and in very good agreement with the recent measurements made by the PLUTO collaboration at PETRA. Predictions are made for higher values ofQ 2 andP 2, where future experiments are planned, and these are compared with the relevant QCD calculations. |
