Nucleon Structure Functions from Neutrino Charged Current Interactions in Bubble Chambers.
The nucleon structure functions F(,2) and xF(,3) have been extracted as functions of the scaling variable x and Q('2)--over a wide range of Q('2)(.1 to 100 Gev('2)/c('2)) --using (nu)((nu)) interactions in Ne-H(,2) filled bubble chambers from low energy wide band experiments at Brookhaven National Laboratory and high energy narrow band experiments at Fermi National Accelerator Laboratory. The extracted values of the structure functions were used to test specific predictions of quark-parton model and scaling violations predicted by QCD. Global fits to the structure functions using Buras-Gaemers parameterization yield a value for the scale parameter (LAMDA) of 245 (+OR-) 840 Mev/c. A moment. analysis of the non-singlet structure function yields (LAMDA) = 500 (+OR-) 480 Mev/c and the slopes of Log-Log moments are consistent with QCD predictions. *National Science Foundation NSF PHY 81-07116.
