Abstract :
Recent results from studies of inclusive and semi-inclusive deep-inelastic lepton scattering are presented. Data with polarization provide the first measurement of the b1(x, Q2) structure function in the deuteron, a five component flavor decomposition of quark helcity distributions in the nucleon, as well as results pertaining to transverse spin physics and deep virtual Compton scattering. Data from unpolarized targets constrain models of quark hadronization and give a measure of parton energy loss in cold nuclear matter.
