New results on the spin dependent structure function $g^{d}_{1}$ of the deuteron

We have made a new measurement of the spin dependent structure function $g^{d}_{1}$ of the deuteron in the kinematic range $0.003 < x < 0.7$ and $1.0 < Q^{2} < 100.0$ GeV$^{2}$. Combining the preliminary results from this measurement with our previous measurements of the deuteron we find...

Sumario:We have made a new measurement of the spin dependent structure function $g^{d}_{1}$ of the deuteron in the kinematic range $0.003 < x < 0.7$ and $1.0 < Q^{2} < 100.0$ GeV$^{2}$. Combining the preliminary results from this measurement with our previous measurements of the deuteron we find the first moment $\Gamma^{d}_{1} = 0.037 \pm 0.006$(stat) $\pm 0.005$(syst) at $Q_{0}^{2} = 10$ GeV$^{2}$. To evolve the structure functions from the measured $Q^{2}$ of the data to 10 GeV$^{2}$ we use a next-to-leading order (NLO) perturbative QCD analysis. Using such QCD evolved structure functions we test the Bjorken and the Ellis-Jaffe sum rule.
