Odderon.

Glueball and oddball resonances lying on the pomeron/odderon trajectories (Chew-Frautchi plot) with threshold and asymptotic behaviour required by analyticity and unitarity are predicted. While the parameters of meson and baryon trajectories can be determined both from the scattering data and from the particles spectra, this is not so for the pomeron (and odderon) trajectory, known only from ...The odderon appears naturally in perturbative QCD. As one can see from Fig. 1 the QCD odderon describes the exchange of three gluons and all the interactions between them. The QCD odderon has the trajectory with the intercept equal to 1, which does not depend on t [16,17]. Hence, the odderon only contributes to the real part of the scattering ...Odderon exchange dominates except at very small transverse momentum, and we find a cross section of about 20 nb at a centre-of-mass energy of 20 GeV. This result is compared with what is currently ...The odderon is defined as a singularity in the complex plane, located at J = 1 when t = 0 and which contributes to the odd crossing amplitude [ 1 , 2 ].

A quasi-real photon interacts as a hadron due to quantum fluctuations into vector mesons or into quark-antiquark pairs. The γγ cross section is composed, Figure 1, by a “soft (VDM)” interaction, which can be described by hadronic phenomenology like the Regge poles, a point like two-photon reaction, γ γ → q q ¯, which is exactly calculable in QED (direct component) and a “hard ... In particle physics, the odderon corresponds to an elusive family of odd-gluon states, dominated by a three-gluon state. When protons collide elastically with protons or with anti-protons at high energies, even or odd numbers of gluons are exchanged. Exchanging an even number of gluons is a crossing-even part of elastic proton-proton and proton-antiproton scattering, while odderon exchange ...the Odderon singularity as does the strong interaction amplitude described in [10]. So, the coincidence of the values of ˆseems accidental, not related with the presence or absence of the Odderon singularity as assumed in [9]. Our conclusion from this reasoning is that no speci c value of the parameter ˆcan be considered asodderon states and so its Green function remain unknown and the relevant technical problems seem great. This is a problem for future studies. 2. 2 pp and pp¯ elastic scattering. Phenomenological description We use the normalization in which the differential cross-section for pp and pp¯ scattering is given byIt is worth to mention again that spin dependent odderon is related to three T-odd gluon TMDs inside a transversely polarized nucleon and the C-odd tri-gluon correlation [19], [20]. In view of these findings and the fact that the spin dependent odderon is the dynamical origin of sea quark Sivers function, one may conclude that spin …

Inspired by the evidence of the odderon exchange recently observed by the D0 and TOTEM Collaborations, a QCD sum rule investigation is performed to study the odderon as a three-gluon bound state.
