Description

The QCD analysis of the Fp2 and Fd2 structure functions obtained by New Muon Collaboration is presented. It leads to precise determination of the gluon distribution down to x=0.008. The re-evaluation of the Gottfried sum, i.e., the integral ∫(Fp2-Fn2)dx/x,based on better knowledge of the Fd2 at low x, gives at Q2=4 GeV2 value 0.235±0.026(total), significantly smaller than 1/3. This result can be interpreted as flavor symmetry violation in the nucleon sea. Similar conclusion was reached from the analysis of Drell-Yan asymmetry measured by NA51 experiment at CERN. copyright 1995 American Institute of Physics
