Leading twist moments of the neutron structure function F2n
We perform a global analysis of neutron F2n structure function data, obtained
by combining proton and deuteron measurements over a large range of kinematics.
From these data the lowest moments (n <= 10) of the leading twist neutron F2n
structure function are extracted. Particular attention is paid to nuclear
effects in the deuteron, which become increasingly important for the higher
moments. Our results for the nonsinglet, isovector (p - n) combination of the
leading twist moments are used to test recent lattice simulations. We also
determine the lowest few moments of the higher twist contributions, and find
these to be approximately isospin independent, suggesting the possible
dominance of ud correlations over uu and dd in the nucleon.Comment: 34 pages, 13 figures. Minor changes. Version to appear in NP
