Scattering and extended vector dominance

U. Maor, E. Gotsman

Research output: Contribution to journalArticlepeer-review


We show that the extended vector-dominance model (EVDM) provides a reasonable fit to the presently available data, both for the photon-photon cross section and for the photon structure function F2 for values of Q225 GeV2. The EVDM approach allows us to circumvent the problem of double counting concerning the hadronic and pointlike pieces of the photon, and yields a value of b2-0.04, for the undetermined coefficient of the second moment of F2.
