Summary
Available analyses on moments of the spin structure function g₁ use different methods and are barely consistent with each other. We present an analysis of Γ₁{sup p} using a method consistent with the studies of Γ₁ⁿ and Γ₁{sup p-n} already published. One result is that the higher twist coefficients seem to alternate signs: the relatively larger twist-6 contribution is partly suppressed by the twist-4 and twist-8 contributions. The size of twist-6 can be explained by the elastic contribution to the moments.
