Measurement of the interference stucture function chiG3(chi) in muon-nucleon scattering

Description

The interference structure function chiG3(chi) has been measured for the first time scattering positive and negative muons of opposite helicity off a carbon target. The chi dependence observed for Q2 between 40 and 180 (GeV/c2) is in good agreement with predictions of the quark-parton model. The measured ratio 2(asub(u)Qsub(u) + asub(d)Qsub(d))/(Qsub(u)2+Qsub(d)2)=1.87 +- 0.25 (stat.) +- 0.24 (syst.) is consistent with the hypothesis of fractional quark charges and determines the sign of Qsub(u)-Qsub(d) to be positive.
