- Abstract
- The energy dependence of the photon-proton total cross section, σtot<sup>γ</sup>p, was determined from e+p scattering data collected with the ZEUS detector at HERA at three values of the center-of-mass energy, W, of the γp system in the range 194<W<296 GeV. This is the first determination of the W dependence of σtot<sup>γ</sup>p from a single experiment at high W. Parameterizing σtot<sup>γ</sup>pαW<sup>2ε</sup>, ε=0.111±0.009(stat.)±0.036(syst.) was obtained. © 2011 Elsevier B.V.
