Abstract

The photon structure function Fγ2(x,Q2) has been measured using data taken by the OPAL detector at e+e− centre-of-mass energies of 91 GeV, 183 GeVand 189 \GeV, in Q2 ranges of 1.5–30.0 GeV2 (LEP1), and 7.0–30.0 GeV2 (LEP2), probing lower values of x than ever before. Since previous OPAL analyses, new Monte Carlo models and new methods, such as multi-variable unfolding, have been introduced, reducing significantly the model dependent systematic errors in the measurement. The results do not conclusively prove, but are completely consistent with, the presence of a rise in Fγ2 at low-x as expected from QCD.
