A measurement of the photon structure function F2(gamma) at Q**2 = 6.8-GeV**2.

The AMY collaboration Kojima, T. ; Nozaki, T. ; Abe, K. ; et al.

The photon structure function F 2 γ has been measured at an average Q 2 value of 6.8 GeV 2 using data collected by the AMY detector at the TRISTAN e + e − collider. The measured F 2 γ is compared with several QCD-based parton density models.

A High Q**2 measurement of the photon structure function F2(gamma)

The AMY collaboration Sahu, S.K. ; Ebara, S. ; Nozaki, T. ; et al.
Phys.Lett.B 346 (1995) 208-216, 1995.
Inspire Record 392701 DOI 10.17182/hepdata.38361

The photon structure function F 2 γ has been measured at average Q 2 values of 73 and 390 GeV 2 using data collected by the AMY detector at the TRISTAN e + e − collider. F 2 γ is observed to be increasing as ln Q 2 . The x -dependence of F 2 γ , where x is the momentum fraction carried by the parton inside the photon, is also measured. The measurements are compared with several parton density models.

Experimental Study of the Photon Structure Function F(2) in the High $Q^2$ Region

The JADE collaboration Bartel, W. ; Cords, D. ; Dietrich, G. ; et al.
Phys.Lett.B 121 (1983) 203-208, 1983.
Inspire Record 180758 DOI 10.17182/hepdata.30781

We report on a measurement of the process e + e − →e + e − + hadrons, where one of the scattered electrons is detected at large angles, with an average Q 2 of 23 GeV. The results are analysed in terms of the photon structure function F 2 and are compared with QCD predictions.
