Measurement of the Charm Structure Function of the Photon at LEP

Charm production is studied in deep-inelastic electron-photon scattering using OPAL data at e+e- centre-of-mass energies from 183 to 209 GeV. Charm quarks are identified by exclusive reconstruction of D* mesons. The cross-section of D* production is measured in a restricted kinematic region, and the...

description Charm production is studied in deep-inelastic electron-photon scattering using OPAL data at e+e- centre-of-mass energies from 183 to 209 GeV. Charm quarks are identified by exclusive reconstruction of D* mesons. The cross-section of D* production is measured in a restricted kinematic region, and then extrapolated to the total charm production cross-section and the charm structure function of the photon. For x>0.1 the measurement is well described by Monte Carlo models and perturbative QCD calculations but for x<0.1 the predictions are lower than the data both in the directly measured region and after the extrapolation.
