Abstract

Physics and Astronomy (miscellaneous)

We have measured the process e+e-→e+e-+hadrons, where one of the scattered electrons was detected at large angles, with Q2 ranging from 7 to 70 (VeV/c)2. The photon structure function F2 γ(x, Q2) was determined at an average Q2 of 23 (GeV/c)2. The measurements were compared to theoretical predictions of the Quark Parton Model and Quantum Chromodynamics. In both models a hadronic part was added. Within the errors the data are in agreement with the QPM using quark masses of 300 MeV/c2 for the light quarks. The data also agree with a QCD calculation including higher order corrections. A fit yielded a {Mathematical expression} value of 140-65 +190 MeV, where the errors include statistical and systematic uncertainties.
