The perturbative odderon in elastic pp and pp̄ scattering
The evidence for the existance of an odderon [1] remains scarce. To date, the best evidence comes from the differential cross section in elastic pp and pp̄ scattering. The pp data show a dip structure at −t ≈ 1.3 GeV while the pp̄ data only flatten off at that point. The odderon, being odd under charge conjugation, couples with different signs to protons and antiprotons and can hence account for ...
متن کاملThe Perturbative Odderon in Quasidiffractive Photon-Photon Scattering
We study the perturbative Odderon in the quasidiffractive process γγ → ηcηc. At high energies this process is dominated by Odderon exchange and can be viewed as the theoretically cleanest test of the perturbative Odderon. We calculate the differential and total cross section, as well as the dependence on the energy and on the photon virtualities taking into account the effects of resummation of...
متن کاملThe Odderon in High Energy Elastic pp Scattering ∗ Hans
We study the Odderon contribution to elastic pp and pp̄ scattering at high energies. Different models for the Odderon–proton coupling are considered and their effects on the differential cross section in the dip region are investigated. We use a Regge fit by Donnachie and Landshoff as a framework and replace its Odderon contribution by the different models. We consider two models for the Odderon...
متن کاملLooking for the Odderon
We propose the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy di ractive photoproduction as a sensitive test of the interference of the Odderon (C = ) and Pomeron (C = +) exchange amplitudes in QCD, that, if measured at HERA, could provide the rst experimental evidence of the Odderon. Contribution to the Proceedings of the 19th International Symposium ...
متن کاملThe odderon and spin - dependence of high energy proton - proton scattering
The sensitivity of the spin dependence of high energy pp scattering, particularly the asymmetry A N N , to the odderon is demonstrated. Several possible ways of determining the spin dependence of the odderon coupling from small-t data are presented.
