Abstract: | It is shown that contact electromagnetic terms in the photo- and electroproduction exclusive channels can account for a substantial amount of the inclusive real and virtual γp total cross sections. In particular, one gets σ(γp)exp?σVMD (?, ω, φ) + σ(contact) for Q2=0 and hence no infinite vector mesons (GVMD) seem to be required. The same result is valid for Q2<0. A parallelism with the parton approach is noted. |
