The Odderon particle is what briefly forms when protons collide in high-energy collisions, and in some cases do not shatter, but bounce off one another and scatter. Protons are made up of quarks ...We apply the formalism developed earlier [1, 2] for studying transverse momentum dependent parton distribution functions (TMDs) at small Bjorken x to construct the small-x asymptotics of the quark Sivers function. First, we explicitly construct the complete fundamental "polarized Wilson line" operator to sub-sub-eikonal order: this object can be used to study a variety of quark TMDs at ...Starting from a simple empirical parametrization of the scattering amplitude, successfully describing the dip-bump structure of elastic pp scattering in t at fixed values of s, we construct a toy model interpolating between missing energy intervals to extract the Odderon contribution from the difference between ¯pp and pp elastic and total cross sections.

The Pomeron describes a colorless exchange with vacuum quantum numbers in the t-channel of hadronic scattering at high energies. The concept was originally formulated for the non-perturbative regime of Quantum Chromodynamics (QCD).At what stage is it necessary to introduce a field theory in the regeon-pomeron-odderon model of hadron interactions?

Frautschi and they do not even bother to introduce the …The Odderon is the C-odd partner of the Pomeron, and in QCD it can be represented as a 3-gluon color singlet state. The small x evolution for the Odderon was derived long time ago [1], [2], [3]. Two solutions for the intercept of the Odderon are known.The Odderon is the leading exchange in hadronic scattering processes at high energies in which negative charge conjugation and parity quantum numbers are transferred in the t-channel. We review the origin of the Odderon in Regge theory, its status in perturbative and nonperturbative Quantum Chromodynamics, as well as its phenomenology.Oct 25, 2005 · Secondly, the Odderon has recently been shown to naturally emerge from the Color Glass Condensate (CGC), a theory for the high-energy asymptotics of QCD. It has been argued that saturation/CGC effects tend to decrease the Odderon intercept, possibly providing an explanation for the lack of experimental evidence for the Odderon so far.
