Odderon-Pomeron interference

Odderon-pomeron Interference

We show that the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy di ractive photoproduction is sensitive to the interference of the Odderon (C = ) and Pomeron (C = +) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using constraints from proton-proton vs. pro...

Charge and Spin Asymmetries from Pomeron-Odderon Interference

We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a π + π − pair. We calculate these asymmetries in the Born approximation of QCD in a kine-matical domain accessible to HERA experiments.

Pomeron/odderon Interference in Diffractive Meson Pairs Production

Hadronic reactions at low momentum transfer and high energies (for chargeeven exchange) are described in QCD in terms of QCD-Pomeron described by the BFKL equation [1]. The charge-odd exchange is less well understood although the corresponding BKP equations [2] have attracted much attention recently [3, 4, 5, 6], thus reviving the relevance of phenomenological studies of the Odderon exchange po...

Pomeron-Odderon interference effects in electroproduction of two pions

We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a π π pair. We calculate these asymmetries originating from both longitudinal and transverse polarizations of the virtual photon, in the framework of QCD and in the Born approximation, in a kinematical domain accessible to HERA experiments. We predict a sizable cha...
