Abstract: (Elsevier)
Cross sections for particle production by the two-photon process for the reactions ee→ee X with X = π 0 or η and X = π + π − or π + π − are calculated exactly by numerical techniques and are compared with predictions of the double equivalent photon approximation (DEPA). Implications of these results as to the validity of the DEPA are discussed and an attempt is made to summarize and clarify some of the earlier criticisms of this approximation.
