Based on the AdS/CFT correspondence, we present a holographic description of various C-odd exchanges in high energy baryon-(anti)baryon scattering, and calculate their respective contributions to the difference in the total cross sections. We show that, due to the warp factor of AdS 5, the single Odderon exchange gives a larger total cross section in baryon-baryon collisions than in baryon ...Mar 24, 2021 · An even-numbered group of gluons is called a ‘pomeron’, while the odd group is dubbed as an odderon.

But in a new study, aIn 1973 the Odderon concept was pushed forward [] which embodies a hypothesis that the leading C-even agent dominating high energy behaviour of the strong interaction cross-sections, the famous Pomeron, may have a C-odd counterpart which can give non-negligible contributions at high energies in contrast to secondary Reggeons \( \rho ,\omega \) etc rapidly dying off with the energy growth.Dec 21, 2022 · In this work, we propose that the odderon is a reggeized odd-glueball tensor spin-3.

The Pomeron is ...Odderon [20-27] correspond respectively to positive and negative C parity. From the QCD point of view, the pomeron is made of and even number of gluons (2, 4, 6, etc) which leads to a (+1) parity whereas the odderon is made of and odd number of gluons (3, 5, 7, etc) corresponding to a (1) parity. The scattering amplitudes can be written as:Starting from the leading Odderon solution of the three gluon system in perturbative QCD we introduce, as a first step towards the transition to the non-perturbative region, an infrared cutoff and use the running QCD coupling constant. In our numerical analysis we find that the fixed cut solution with intercept one persists, hinting at a physical Odderon with intercept one and a small t-slope.Un tipo particular de cuasipartícula se llama el odderon, predicho para existir en los años 70.
