Stronger $C$-odd color charge correlations in the proton at higher energy
Abstract
The non-forward eikonal scattering matrix for dipole-proton scattering at high energy obtains an imaginary part due to a -odd three gluon exchange. We present numerical estimates for the perturbative Odderon amplitude as a function of dipole size, impact parameter, their relative azimuthal angle, and light-cone momentum cutoff . The proton is approximated as , where is a non-perturbative three quark model wave function while the gluon emission is computed in light-cone perturbation theory. We find that the Odderon amplitude increases as decreases from 0.1 to 0.01. At yet lower , the reversal of this energy dependence would reflect the onset of universal small- renormalization group evolution.
