Experimental determination of the evolution of the Bjorken integral at low Q2

Description

We extract the Bjorken integral Γ1p-n in the range 0.17 < Q2 < 1.10 GeV2 from inclusive scattering of polarized electrons by polarized protons, deuterons and 3He, for the region in which the integral is dominated by nucleon resonances. These data bridge the domains of the hadronic and partonic descriptions of the nucleon. In combination with earlier measurements at higher Q2, we extract the non-singlet twist-4 matrix element f2
