Odderon
Below we will try to trace almost a half-of-century history of the Odderon concept and attempts and e orts to nd its experimental manifestations. 1Speaker 2Later the Odderon option as formulated in [1] was dubbed (after serious mod cations) the "Maximal Odderon" in contrast to other Odderon incarnations (e.g. as a C-odd Reggeon). The existence of an Odderon is a natural prediction of the Quantum Chromodynamics (QCD), has a C-odd parity and determines the hadronic cross section difference between the direct and crossed channel processes at very high energies (for a review see Ref. ).

Abstract Although the Odderon is an unambiguous pre-diction of Quantum Chromodynamics, its existence still was not confirmed experimentally. One of the processes where the Odderon contribution is expected to be dominant is the diffractive photoproduction of tensor mesons. In this paper we study the diffractive f2(1270) …It's an odderon, a particle that's even more odd than its name suggests, and it may have recently been detected at the Large Hadron Collider, the most powerful atom …the scattering amplitude describing Odderon exchange enters quadratically in the cross section. This observation lead to the suggestion in Ref. [14], that the study of observ-ables where Odderon effects are present at the amplitude level - and not at the squared amplitude level - is mandatory to get a convenient sensitivity to a rather small ...odderon 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.

In this paper we extend our recent nonperturbative functional renormalization group analysis of Reggeon field theory to the interactions of Pomeron and Odderon fields. We establish the existence of a fixed point and its universal properties, which exhibits a novel symmetry structure in the space of Odderon-Pomeron interactions. As in our …CERN's Large Hadron Collider confirms the discovery of the "odderon", a subatomic compound of three gluons that forms when protons collide violently but aren't destroyed; the odderon was theorized in the early 70s and finally detectedWe summarize the results of including running coupling corrections into the nonlinear evolution equation for diffractive dissociation. We also document a prediction that the NLO QCD odderon intercept is zero resulting from a discussion at the Diffraction 2012 Workshop.odderon states and so its Green function remain unknown and the relevant technical problems seem great.

The U.S. Department of Energy's Office of Scientific and Technical Informationas we see from gure1, odderon exchange is not the only C= 1 exchange contribution. Thus, a careful analysis of all contributing C= +1 and C= 1 exchanges is necessary in order to assess the r^ole of the odderon. In this paper we present such a description as is a prerequisite for an experimental search for odderon e ects in the reaction (1.1).The Odderon is now a fundamental object in QCD and CGC and it has to be found experimentally if QCD and CGC are right. In the present talk, we show how to find it at RHIC and LHC.

The odderon intercept appeared to be smaller than unity, meaning that C-odd amplitudes should decrease with energy. In a following analysis, however, it was discovered by Bartels, Lipatov and Vacca (BLV) [19] that the normalizability condition of the holomorphic wave functions may be relaxed, leading to a new odderon solution, having a flat ...We explore the possibility of observing odderon exchange in the pp→ppK+K− and pp→ppμ+μ− reactions at the LHC.
