Abstract: (Elsevier)
Inclusive γ ∗ γ interactions to hadronic final states where one scattered electron or positron is detected in the electromagnetic calorimeters have been studied in the LEP 1 data taken by ALEPH from 1991 to 1995. The event sample has been used to measure the hadronic structure function of the photon F 2 γ in three bins with 〈 Q 2 〉 of 9.9, 20.7 and 284 GeV 2 .- electron positron: colliding beams
- exchange: two-photon
- photon photon: inclusive reaction
- photon: structure function
- momentum transfer dependence
- x-dependence
- parametrization
- momentum spectrum: parton
- hadron: photoproduction
- ALEPH
