Spin asymmetries A 1 and structure functions g 1 of the proton and the deuteron from polarized high energy muon scattering
We present the final results of the spin asymmetries A 1 and the spin structure functions g 1 of the proton and the deuteron in the kinematic range 0.0008<x<0.7 and 0.2<Q 2 <100 GeV 2 . For the determination of A 1 , in addition to the usual method which employs inclusive...

| Sumario: | We present the final results of the spin asymmetries A 1 and the spin structure functions g 1 of the proton and the deuteron in the kinematic range 0.0008<x<0.7 and 0.2<Q 2 <100 GeV 2 . For the determination of A 1 , in addition to the usual method which employs inclusive scattering events and includes a large radiative background at low x, we use a new method which minimizes the radiative background by selecting events with at least one hadron as well as a muon in the final state. We find that this hadron method gives smaller errors for x<0.02, so it is combined with the usual method to provide the optimal set of results. |
