An upcoming transverse spin experiment at Jefferson Lab

  After many years of preparation, the Neutron Transversity Experiment
(E06-010) is about to collect data from Oct. 2008 to Feb. 2009 at DOE's
Thomas Jefferson National Accelerator Facility.

  Since the late 70's, a rather strange target single-spin asymmetry
phenomena has been observed, in which hadron fragments from a quark in a
transversely polarized nucleon seem to have a left-right preference. 
Indeed, recent deep-inelastic scattering experiments from HERA and CERN have
clearly demonstrated that a quark in transversely polarized proton can
manage to tell left from right.

   Does such a target single-spin asymmetry depend on a quark's flavor ?
The upcoming experiment using a polarized neutron target (He-3) seeks to
provide the answer. Members of the P25 group at LANL have been playing
leading roles in this experiment.
