Description
The Jefferson Lab Angular Momentum (JAM) collaboration is a
new initiative aimed at the study of the angular-momentum-dependent
structure of the nucleon. First results on the determination of
spin-dependent parton distribution functions from world data on
polarized deep-inelastic scattering will be presented and compared
with previous determinations from other groups. Different aspects of
global QCD analysis will be discussed, including effects due to the
nuclear structure of deuteron and Helium targets, target-mass
corrections and higher twist contributions to the g1 structure
function as well as the g2 structure function.
