A sign change of the moment at n=0 of the polarized structure function g_1^{p}

The sum rule for the structure function g_1^{p} which is related to the cross section of the photo-production is used to show that a sign change of the integral corresponding to the appropriately defined moment at n=0 where the integral is cut at the point x=x_c(Q^2) occurs at very small...
