- Summary
- Jefferson Lab experiment E97-103 measured the spin structure function gn2 from a Q^2 of 0.58 to 1.36 with a nearly constant x of 0.2. Combining this data with a fit to the world gn1 data, the size of higher twist contributions to gn2 can be extracted using the Wandzura-Wilczek relation. These higher twist contributions result from quark-gluon correlations and are expected to be larger as Q^2 decreases. This experiment was performed in Hall A with a longitudinally polarized electron beam and a high density polarized He-3 target. The physics motivation and an overview of the experiment will be presented.
