Precision Measurement of R = $\sigma^-$l / $\sigma^- T$ and F(2) in Deep Inelastic Electron Scattering

Dasu, S. ; De Barbaro, P. ; Bodek, A. ; et al.
Phys.Rev.Lett. 61 (1988) 1061, 1988.
Inspire Record 262063 DOI 10.17182/hepdata.20079

We report new results on a precision measurement of the ratio R=σLσT and the structure function F2 for deep-inelastic electron-nucleon scattering in the kinematic range 0.2≤x≤0.5 and 1≤Q2≤10 (GeV/c)2. Our results show, for the first time, a clear falloff of R with increasing Q2. Our R and F2 results are in good agreement with QCD predictions only when corrections for target-mass effects are included.

Measurement of the Photon Structure Function f(2)Gamma at Q**2 from 7-GeV/c**2 to 70-GeV/c**2

The TASSO collaboration Althoff, M. ; Braunschweig, W. ; Gerhards, R. ; et al.
Z.Phys.C 31 (1986) 527, 1986.
Inspire Record 228251 DOI 10.17182/hepdata.15858

We have measured the processe+e−→e+e−+hadrons, where one of the scattered electrons was detected at large angles, withQ2 ranging from 7 to 70 (VeV/c)2. The photon structure functionF2γ(x, Q2) was determined at an averageQ2 of 23 (GeV/c)2. The measurements were compared to theoretical predictions of the Quark Parton Model and Quantum Chromodynamics. In both models a hadronic part was added. Within the errors the data are in agreement with the QPM using quark masses of 300 MeV/c2 for the light quarks. The data also agree with a QCD calculation including higher order corrections. A fit yielded a\(\Lambda _{\overline {MS} } \) value of 140−65+190 MeV, where the errors include statistical and systematic uncertainties.
