Description
Significant progress has recently been made, both experimentally and theoretically, in extracting the neutron structure function from deuterium data. Of particular note are the new CTEQ-JLab (CJ) nuclear corrections for large x PDF extraction, and the Jefferson Lab "BONUS" experiment, where a novel tagged proton spectator approach was employed to isolate the neutron target in electron-deuteron scattering. The BONUS data, combined with a wealth of precision deuterium data from Jefferson Lab, SLAC, and NMC, the latter now all with state-of-the-art CJ nuclear corrections applied, has been used to re-evaluate the Gottfried Sum rule integrand F2n-F2p. Results of this analysis will be presented, and compared with the well-known results from NMC which lacked precision neutron extraction.
