Query: Transverse single spin asymmetries at small x and the anomalous magnetic
  moment   We show that in the Mclerran-Venugopalan model, an axial asymmetrical valence
quark distributions in the transverse plane of a transversely polarized proton
can give rise to a spin dependent odderon. Such polarized odderon is
responsible for the transverse single spin asymmetries(SSAs) for jet production
in the backward region of pp collisions and open charm production in
semi-inclusive DIS process.
