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.

Measurement of the Proton Structure Function F(2) in Muon - Hydrogen Interactions at 120-GeV and 280-GeV

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.
Phys.Lett.B 105 (1981) 315-321, 1981.
Inspire Record 167336 DOI 10.17182/hepdata.31046

The proton structure function F 2 has been measured in the range 2.5 ⪕ Q 2 ⪕ 170 GeV 2 and 0.03 ⪕ x ⪕ 0.65 . Scaling violation is clearly seen in the data. Results of fits to leading-order QCD are presented, together with values of the scale-breaking parameter λ.

First Measurement of the Photon Structure Function F2

The PLUTO collaboration Berger, Christoph ; Genzel, H. ; Grigull, R. ; et al.
Phys.Lett.B 107 (1981) 168-172, 1981.
Inspire Record 167681 DOI 10.17182/hepdata.31043

Using data taken at PETRA we present results on deep inelastic electron photon scattering at momentum transfers 1 < Q 2 < 15 GeV 2 . The results are expressed in terms of the photon structure function F 2 and are compared with QCD predictions and “hadronic” models of the photon. The pointlike component of the photon is found to be dominant.

A Measurement of the Nucleon Structure Function From Muon Carbon Deep Inelastic Scattering at High $Q^2$

The BCDMS collaboration Bollini, D. ; Frabetti, P.L. ; Heiman, G. ; et al.
Phys.Lett.B 104 (1981) 403-408, 1981.
Inspire Record 166160 DOI 10.17182/hepdata.71276

Deep inelastic scattering cross sections have been measured with the CERN SPS muon beam at incident energies of 120 and 200 GeV. Approximately 100 000 events at each energy are used to obtain the structure function F 2 ( x , Q 2 ) in the kinematic region 0.3< x <0.7 and 25 GeV 2 < Q 2 <200 GeV 2 .

Measurement of the Energy and X Dependence of the Y Distributions in Anti-neutrino Interactions

Benvenuti, A.C. ; Bobisut, F. ; Cline, D. ; et al.
Phys.Rev.Lett. 42 (1979) 149, 1979.
Inspire Record 7154 DOI 10.17182/hepdata.21899

Analysis of 5180 ν¯ interactions shows a variation with energy of the inelasticity (y) distributions over the range 10 to 220 GeV and a dependence on the scaling variable x. From these data are obtained the approximate x dependence of the sea quarks and a limit on the strength of right-handed coupling between the u quark and a massive b quark.
