Measurements of the g{sup p}{sub 1} spin structure function
- Tel Aviv Univ., Tel Aviv (Israel)
The spin structure function g{sub 1}{sup p} of the proton has been measured b deep inelastic scattering of polarized muons from polarized protons. The data were taken over the kinematic range 0.003 {le} x B{sub j} {le} 0.7 and 1 GeV{sup 2} {le} Q{sup 2} {le} 60 GeV{sup 2}. The first moment {Gamma}{sub 1}{sup p} = {integral}{sub 0}{sup 1}G{sub 1}{sup p}(x)dx was evaluated and compared to the I Ellis-Jaffe sum rule. The consistency of existing proton deuteron and neutron data is discussed. Combination of the data allows a test the fundamental Bjorken sum rule which is confirmed at the level of 10% of its theoretical value, when high QCD corrections are considered. The contribution of the quark spins to the nucleon spin is evaluated within the quark-parton model.
