Abstract
We report on an experimental determination of the Q2-dependence of the Bjorken sum using data from Jefferson Lab Hall A and Hall B in the range 0.16 < Q2 < 1.1 GeV2. A twist analysis is performed. Overall, the higher twist corrections are found to be small due to a cancellation between the twist 4 and 6 terms.
