Spin Structure of the Deuteron - New Results from CLAS
ORAL
Abstract
The EG1B experiment, which was carried out at Jefferson Lab using the CLAS detector, measured double polarization asymmetries in the nucleon resonance region and above ( $1.08 GeV < W < 3.0 GeV$ ). We used a longitudinally polarized electron beam of various energies incident on longitudinally polarized proton and deuteron targets. The large kinematic coverage of the experiment ( $0.05 GeV^2 < Q^2 < 5.0 GeV^2$ ) will help us to understand the spin structure of the nucleon especially in the transition region between the hadronic degrees of freedom and the quark-gluon degrees of freedom. In this presentation new preliminary results on $A_1$ and $A_2$ for the deuteron will be shown.
