Recent experimental results from SLAC on the nucleon spin structure
Description
Recent precise measurements at SLAC of the spin structure function g1 for proton using deep inelastic scattering of polarized electrons from a polarized ammonia target are presented. The first moment evaluated at the average experimental Q2 = 3 (GeV/c)2 is determined, in agreement with previous results but well below the Ellis-Jaffe sum rule prediction. The analysis of this results in term of Quark Parton Model implies that the quarks carry 0.29±0.10 of the nucleon helicity. (author). 16 refs., 3 figs
