Measurement of the Photon Structure Function F2gamma at Low x
The OPAL Collaboration, K. Ackerstaff et al
Abstract
Deep inelastic electron-photon scattering is studied using e+e- data collected by the OPAL detector at centre-of-mass energies sqrtsee ~ MZ0. The photon structure function F2gamma(x,Q2) is explored in a Q2 range of 1.1 to 6.6 GeV/c2 at lower x values than ever before. To probe this kinematic region events are selected with a beam electron scattered into one of the OPAL luminosity calorimeters at scattering angles between 27 and 55 mrad. A measurement is presented of the photon structure function F2gamma(x,Q2) at <Q2> = 1.86 GeV2 and 3.76 GeV2 in five logarithmic x bins from 0.0025 to 0.2.
