Odderon-pomeron Interference
نویسندگان
چکیده
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. proton-antiproton elastic scattering. Measurements of this asymmetry at HERA could provide the rst evidence for the presence of Odderon exchange in the high energy limit of strong interactions. Submitted to Physics Letters B.

odderon discovery via observation of charge asymmetry in the diffractive π + π − production at HERA
The interference between the Pomeron and possible odderon mechanisms of diffractive π+π− photoproduction results in charge asymmetry of the produced pions. Without referring to any particular model of the odderon, we establish how the kind of charge asymmetry depends on the helicity structure of Pomeron and odderon mediated production of dipions. Focusing on region Mπ+π− = 1.1 ÷ 1.5 GeV, where ...
متن کاملPomeron Odderon interference in production of π+π− pairs at LHC
In the context of hadronic interactions, events with rapidity gaps are dominated by the exchange of a C-even color singlet state, called the Pomeron. Within perturbative QCD the Pomeron is built by the exchange of two gluons at lowest order. While the Pomeron has acquired a good standing, the status of its C-odd partner – the Odderon – is less safe. Although it is needed e.g. to describe proper...

We review the results of our studies on the charge and the spin asymmetries in the electroproduction of π + π − which are the observables sensitive to the Pomeron-Odderon interference.
متن کاملLooking for the Odderon in photon collisions
At high energies amplitudes of reactions with rapidity gaps in hadronic interactions are dominated by the exchange of a color singlet, C-even state – called the Pomeron. In the language of perturbative QCD – at lowest order – the Pomeron can be described as the exchange of two gluons in the color singlet state. In contrast to the very well settled notion of the Pomeron, the status of its C-odd ...
متن کاملCharge 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.
