| Sumario: | The e+e− → e+e−hadrons reaction, where one of the two electrons is detected in a low polar-angle calorimeter, is analysed in order to measure the hadronic photon structure function <math><msubsup is="true"><mi is="true">F</mi><mn is="true">2</mn><mi is="true">γ</mi></msubsup></math>. The full high-energy and high-luminosity data set, collected with the L3 detector at centre-of-mass energies 189 GeV ≼ √s ≼ 209 GeV, corresponding to an integrated luminosity of 608 pb−1 is used. The Q2 range 11 GeV2 ≼ Q2 ≼ 34 GeV2 and the x range 0.006 ≼ x ≼ 0.556 are considered. The data are compared with recent parton density functions. |
