Abstract

The first experimental evidence of quark-hadron duality for the spin asymmetry A1(x) of the proton was observed for Q2 between 1.6 and 2.9 GeV2. Thus, the spin asymmetries measured int he nucleon resonance region at W2≤4 GeV2 were found to be in agreement with the spin asymmetries measured in the DIS region at larger W2. Such experimental findings indicates that the description of the spin asymmetry in terms of quark degrees of freedom was on average valid also in the nucleon resonance region within the Q2 range probed by the present experiment.

N2 - The first experimental evidence of quark-hadron duality for the spin asymmetry A1(x) of the proton was observed for Q2 between 1.6 and 2.9 GeV2. Thus, the spin asymmetries measured int he nucleon resonance region at W2≤4 GeV2 were found to be in agreement with the spin asymmetries measured in the DIS region at larger W2. Such experimental findings indicates that the description of the spin asymmetry in terms of quark degrees of freedom was on average valid also in the nucleon resonance region within the Q2 range probed by the present experiment.

AB - The first experimental evidence of quark-hadron duality for the spin asymmetry A1(x) of the proton was observed for Q2 between 1.6 and 2.9 GeV2. Thus, the spin asymmetries measured int he nucleon resonance region at W2≤4 GeV2 were found to be in agreement with the spin asymmetries measured in the DIS region at larger W2. Such experimental findings indicates that the description of the spin asymmetry in terms of quark degrees of freedom was on average valid also in the nucleon resonance region within the Q2 range probed by the present experiment.
