Abstract

The hadronic structure function of the photon F₂ ^γ (x, Q²) is measured as a function of Bjorken x and of the photon virtuality Q² using deep-inelastic scattering data taken by the OPAL detector at LEP at e⁺e^- centre-of-mass energies from 183 to 209 GeV. Previous OPAL measurements of the x dependence of F₂ ^γ are extended to an average Q² of (Q²) = 780 GeV² using data in the kinematic range 0.15 < × < 0.98. The Q² evolution of F₂ ^γ is studied for 12.1 < (Q²) < 780 GeV² using three ranges of x. As predicted by QCD, the data show positive scaling violations in F₂ ^γ with F₂ ^γ (Q²)/α = (0.08 ± 0.02_-0.03 ^+0.05)+(0.13 ± 0.01 _-0.01 ^+0.01) 1n Q², where Q² is in GeV², for the central x region 0.10-0.60. Several parameterisations of F₂ ^γ are in qualitative agreement with the measurements whereas the quark-parton model prediction fails to describe the data.
