A measurement of σtot(γp) at sqrt(S) = 210 GeV
Abstract
The total photoproduction cross section is determined from a measurement of electroproduction with the ZEUS detector at HERA. The Q2 values of the virtual photons are in the range 10 -7< Q2<2×10 -2 GeV 2. The γp total cross section in the γp centre of mass energy range 186-233 GeV is 154 ± 16 (stat.) ± 32 (syst.) μb.
