Odderon.

Sep 19, 2022 · However, when combining this signal with the Odderon signals from the ReBB model in the $$0.37 \le -t \le 1.2$$ GeV $$^2$$ four-momentum-transfer range at $$\sqrt{s} = $$ 1.96, 2.76 and 7 TeV, it turns out that the combined significance is dominated not by the new 8 TeV but by that of earlier 7 TeV TOTEM data, that carry an even larger Odderon ... By using the model parameters, the Chew-Frautschi plot of the tensor odderon Regge trajectory is evaluated. As a result, the odderon spin-3 mass is predicted to be 3.2 GeV. In addition, the total cross-section of our model is compatible with the results from TOTEM and its extrapolation from D0 collaboration.Enter the email address you signed up with and we'll email you a reset link.The name Odderon for the first time was proposed by D. Joynson, E. Leader, B. Nico-lescu and C. Lopez in [15] two years after the first paper of Łukaszuk and B. Nicolescu . The detailed investigation of unitarity and analyticity of Maximal Odderon was performed by P. Gauron, Łukaszuk and B. Nicolescu [16]. It was shown in this paper that ...

We discuss the definition and the energy evolution of scattering amplitudes with C-odd (“odderon”) quantum numbers within the effective theory for the color glass condensate (CGC) endowed with the functional, JIMWLK, evolution equation.We explicitly construct gauge-invariant amplitudes describing multiple odderon exchanges in the …

This is the odderon that the CERN team found evidence of. But in this special kind of collision, the number of gluons exchanged is important. If an even number of gluons are exchanged, the ...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 previous analysis, this part of our program aims at the ...

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 advent of quantum chromodynamics (QCD) led theorists to predict the existence of the odderon in 1973. Proving its existence has been a major experimental challenge, however, requiring detailed measurements of protons as they glance off one another in high-energy collisions. While most high-energy collisions cause protons to break into their ...

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 most spectacular signature of the Odderon is the predicted difference between the differential cross-sections for proton-proton and antiproton ...In the present paper, we extend the Froissaron-Maximal Odderon (FMO) approach at t different from 0. Our extended FMO approach gives an excellent description of the 3266 experimental points considered in a wide range of energies and momentum transferred. We show that the very interesting TOTEM results for proton–proton differential cross-section in the range 2.76–13 TeV, together with the ...We show that the asymmetry in the fractional energy of charm versus anticharm jets produced in high energy diffractive photoproduction is sensitive to the interference of the Odderon (C = {minus}) and Pomeron (C = +) exchange amplitudes in QCD. We predict the dynamical shape of the asymmetry in a simple model and estimate its magnitude to be of the order 15% using an Odderon coupling to the ...Odderon [20-27] correspond respectively to positive and negative C parity. From the QCD point of view, the pomeron is made of and even number of gluons (2, 4, 6, etc) which leads to a (+1) parity whereas the odderon is made of and odd number of gluons (3, 5, 7, etc) corresponding to a (1) parity. The scattering amplitudes can be written as:

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.

Add to this the fact that the Odderon interacts oppositely with antiparticles than with particles, the way to discover of the Odderon is open. Any significant difference between elastic particle-particle scattering and elastic particle-antiparticle scattering in the diffractive dip region at the same collision energy is evidence for the Odderon.Journal Article: Odderon and polarization phenomena in QCD Odderon and polarization phenomena in QCD.

As a result of his rank, he received startup money to put together a team of researchers to work on discovering odderon. The researchers discovered the quasiparticle as a result of analyzing proton collisions at high speeds. In the same year, Royon was the recipient of the Humboldt Prize for his "pioneering work."Jan 31, 2018 · Physicists have imagined the existence of the odderon for many decades, but until the LHC began operating at its highest energies in 2015, the odderon remained mere conjecture. The data collected and presented in the new paper was collected at 13 teraelectronvolts (TeV), the fastest scientists have ever been able to collide protons. We study the odderon contribution to elastic pp and \ (p\bar {p}\) scattering at high energies. Different models for the odderon-proton coupling are considered and their effects on the differential cross section in the dip region are investigated. We use a Regge fit by Donnachie and Landshoff as a framework and replace its odderon ...Based on the assumption that, the Pomeron is a sum of Regge multipoles, each of which corresponds to a finite gluon ladder, we suggest a way to search the Odderon by studying the diffractive ...We find that the odderon amplitude increases as x decreases from 0.1 to 0.01.

It has been shown [3] that the suppression of the odderon contribution in pp (p¯p) scattering can be explained by diquark clustering in the proton, provided the diquark is sufficiently small ≤ 0.3 fm.March 8. An Odd New Result of Hungarian and Swedish Researchers: Discovery of a long awaited but totally surprising new particle, the Odderon.The Odderon effects remained elusive for a long time, due to lack of a definitive and statistically significant experimental evidence. A direct way to probe the Odderon in elastic scattering is by comparing the differential cross-section of particle-particle and particle-antiparticle scattering at sufficiently high energies [3, 4].the maximal Odderon which could be tentatively caught with now existing means. For instance, a latest embodiment of the maximal Odderon doctrine, the "Froissaron-maximal Odderon" model (FMO), yielded the value of the parameter ρ. = ReTpp(s,0)/ImTpp(s,0) = O(0.1) almost exactly coinciding with its value published by the TOTEM Collabo-ration ...The odderon remains an elusive object, 33 years after its invention.

Using a model with mildly energy dependent form factors as input and performing full eikonalization before we compare with the data, the answer that we find from a careful examination of the various options is that the odderon is indeed necessary if: 1) we trust the ISR pp data to be precise enough that their comparison with the collider data ...as 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).Jun 1, 1991 · The odderon amplitude without spin-flip falls off with decreasing diquark radius.

If the odderon didn't exist, then DZero and TOTEM should have seen the same scattering patterns in their data after adjusting for the energy differences between the Tevatron and LHC.
