Classical odderon in QCD at high energies

We show that the weight functional for color sources in the classical theory of the color glass condensate (CGC) includes a term which generates odderon excitations. Remarkably, the classical origin of these excitations can be traced to the random walk of partons in the two dimensional space spanned by the SU(3) Casimirs. We compute dipole and baryon odderon operators in the CGC and show that contributions from the classical color sources to these are suppressed in the limit of very large parton densities.
