Gluons “glue” the quarks together to “hadrons”, particles that are held together by the strong …that carry an even larger Odderon effect. Thus, in any prac-tical terms, within the framework of the ReBB model, the Odderon signal in the limited 0.37 ≤−t ≤ 1.2GeV2 and 1.96 ≤ √ s ≤ 8 TeV kinematic region is not a probability, but a certainty. We show also that the H(x) scaling version of the ReBB model works reasonably well at 8 ...In the high energy regime of Quantum Chromodynamics (QCD) novel effective degrees of freedom, reggeized gluons, arise.
