Nucleon EM Form Factors and its Spin Structure

The powerpoint presentation highlights the very active experimental program on nucleon form factors and spin factors, which is attributed to the development of a polarized beam (> 100 μA, > 75%). Other points noted in the summary include: GEp: precise data set up to Q2 = 5.6 (GeV/c)2 charge FF differs from magnetization FF - Q2 = 9 (GeV/c)2 planned; GEn: 3 successful experiments, precise data anticipated - higher Q2 possible and approved; GMn: Q2 < 1 data from 3He(e,e') - high Q2 data from 2H(e,e',n)/2H(e,e'p) in analysis; A1n: first accurate measurements at intermediate x-values; and need active theory support (radiative corrections, lattice QCD, relativistic wf, etc.)
