Measurement of the Q^2-evolution of the Bjorken integral and extraction of an effective strong coupling constant at low Q^2

arXiv:nucl-ex/0501015 · doi:10.1016/j.nuclphysa.2005.03.115

Abstract

We report on the measurement of the Bjorken sum in the range 0.16<Q^2<1.1 GeV^2. The extraction of an effective strong coupling constant is then discussed.

Contribution to the proceedings of the Baryons04 conference. To be published in the journal Nuclear Physics A
