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 and which does not depend on t[16, 17]. Hence, the Odderon only contributes to the real part of the scattering amplitude. For an estimate we will use the following formOdderon 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 ...still weak, experimental evidence for the odderon was found as a difference between the dif-ferential cross sections for elastic ppand pp¯ scattering at √ s= 53 GeV at CERN ISR 2. A natural difficulty in detecting odderon effects is the fact that, in general, the odderon and the pomeron contribute to the scattering amplitude at the same time.

Low-x is an annual workshop whose spirit is to favour fruitful and informal discussions between experimentalists and theorists in low-x, diffractive hadronic physics and exciting problems in QCD at HERA, Tevatron and LHC. Low-x has been held since DESY (1993), then Saclay (May 1994), Cambridge (July 1995), Durham (June 1996), Madrid (June 1997 ...Recent results are summarized from the TOTEM experiment at CERN LHC, including measurements of the total, elastic and inelastic cross-sections, the nuclear …Odderon asymptotics emerged for the first time in Ref. [1] and is nowadays usually associated with C = -1 exchange in t-channel. Although the studies in QCD [2, 3] (see Refs. [4, 5] for further references) support existence of C=-1 exchange (QCD Odderon), it should be stressed that such exchange need not be mandatory for the Odderon type behavior.HISTORY The odderon was born in 1973 and it was then motivated by the surprising data provided by the ISR : the increase of the total cross-sections which seemed to show that the In2s Froissart-Martin bound could be saturated. This led Lukaszuk and Nic~lescuI to the hypothesis that the strong interactions could be as strong as possible, i.e ...The general agreement with the present experimental data is also briefly discussed. The last part of the talk is devoted to the predictions of the Odderon approach at LHC energies. We expect new physics to occur at LHC energies. We will therefore present strong arguments in favour of the adoption of both pp and p options at LHC.

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.... Global Survey. In just 3 minutes help us understand how you see arXiv. TAKE SURVEY.In this experimental observation, the TOTEM proton-proton data in the region of the diffractive minimum and maximum was extrapolated from 13, 8, 7 and 2.76 TeV to 1.96 TeV and compared this to D0 data at 1.96 TeV in the same t-range giving an odderon significance of 3.4 σ.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 overall … ….

Their couplings with various proton polarization states can be completely parametrized by the generalized transverse momentum dependent distributions (GTMDs) [34].

Numerical estimates for the cross sections turn out to be very different in these two approaches: the nonperturbative Odderon models tend to give substantially larger cross sections [2 ... usps rural pay scale 2023osu big 12domino's pizza chino valley menu Note that in the Ref.

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 ...We compare the purely diffractive contribution (odderon-pomeron fusion) to the photoproduction contribution (photon-pomeron fusion). The theoretical results are calculated within the tensor-pomeron and vector-odderon model for soft reactions. We include absorptive corrections at the amplitude level. raindrop impressionsbest wow nameplate addonentry level medical records clerk salary As nouns the difference between charge and odderon is that charge is the scope of someone's responsibility while odderon is the hypothetical counterpart of the pomeron, carrying odd charge parity. As a verb charge is to place a burden upon; to assign a duty or responsibility to. As a proper noun Chargé is a commune in the Indre-et-Loire department in France.
