Abstract:
Previous Drell-Yan and deep-inelastic lepton scattering experiments have
established that the momentum and spin distributions of sea quarks
in the nucleon are not simple, and exhibit unexpected structure. A new
Drell-Yan experiment at Fermilab, E906, is being mounted to carry out
precision measurements of the Drell-Yan cross sections on 1H, 2H
and a collection of heavier nuclei. The main point of the physics
program is the study of the anti-quark distribution in the middle
range of Bjorken $x$ in both the nucleon and in nuclei. In addition,
the data can be used to study quark energy loss in nuclear matter.
