Abstract

We present a new measurement of the virtual photon proton asymmetry A^p₁ from deep inelastic scattering of polarized muons on polarized protons in the kinematic range 0.0008 < x < 0.7 and 0.2 < Q² < 100 GeV². With this, the statistical uncertainty of our measurement has improved by a factor of 2 compared to our previous measurements. The spin-dependent structure function g_p1 is determined for the data with Q² > 1 GeV². A perturbative QCD evolution in next-to-leading order is used to determine g^p₁(x) at a constant Q². At Q2 = 10 GeV² we find, in the measured range, ∫^0.7_0.003 g^p₁(x)d x = 0.139 ± 0.006(stat) ± 0.008(syst) ± 0.006 (evol). The value of the first moment Γ^p1 = ∫¹₀g^p₁(x)dx of g^p₁ depends on the approach used to describe the behaviour of g^p₁ at low x. We find that the Ellis-Jaffe sum rule is violated. With our published result for Γ^d₁ we confirm the Bjorken sum rule with an accuracy of ≈ 15% at the one standard deviation level.

N2 - We present a new measurement of the virtual photon proton asymmetry Ap1 from deep inelastic scattering of polarized muons on polarized protons in the kinematic range 0.0008 < x < 0.7 and 0.2 < Q2 < 100 GeV2. With this, the statistical uncertainty of our measurement has improved by a factor of 2 compared to our previous measurements. The spin-dependent structure function gp1 is determined for the data with Q2 > 1 GeV2. A perturbative QCD evolution in next-to-leading order is used to determine gp1(x) at a constant Q2. At Q2 = 10 GeV2 we find, in the measured range, ∫0.70.003 gp1(x)d x = 0.139 ± 0.006(stat) ± 0.008(syst) ± 0.006 (evol). The value of the first moment Γp1 = ∫10gp1(x)dx of gp1 depends on the approach used to describe the behaviour of gp1 at low x. We find that the Ellis-Jaffe sum rule is violated. With our published result for Γd1 we confirm the Bjorken sum rule with an accuracy of ≈ 15% at the one standard deviation level.
