A Measurement of the photon structure function F2

The AMY collaboration Sasaki, T. ; Yamagishi, Y. ; Tanaka, R. ; et al.
Phys.Lett.B 252 (1990) 491-498, 1990.

The photon structure function F 2 has been measured at average Q 2 values of 73,160 and 390 ( GeV c ) 2 . We compare the x dependence of the Q 2 = 73 ( GeV c ) 2 data with theoretical expectations based on QCD. In addition we present results on the Q 2 evolution of the structure function for the intermediate x range (0.3⩽ x ⩽0.8). The results are consistent with QCD.

Determination of the Quark Density Ratio $d(x)/u(x)$ in the Proton

The Aachen-Bonn-CERN-Munich-Oxford collaboration Allen, P. ; Grassler, H. ; Lanske, D. ; et al.
Phys.Lett.B 103 (1981) 71-74, 1981.
Inspire Record 10562 DOI 10.17182/hepdata.31204

Data from an exposure of BEBC filled with hydrogen to a wideband neutrino beam are analysed to yield the structure function F v p 2 ( x ) for x > 0.2. Using our results in combination with data from electron-proton and muon-proton scattering, the quark density ratio d/u is determined as a function of x . The dominance u at large x is clearly seen. The results are compared with theoretical predictions.
