Nuclear Physics Seminars

Over the past decade, many experiments have measured the nucleon spin structure functions using polarized deep inelastic scattering, both in the US and in Europe. After a brief survey of these efforts, the results from SLAC experiments E155 and E155x will be presented. This pair of experiments has measured g1 and g2 of the proton and the deuteron with high precision and over a large kinematic range, providing the best measurements available. In the discussion of these measurements, special attention will be given to the radiative corrections, which have a significant impact on the measured results and also on statistical and on systematic errors.
