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."evolved Odderon at a electron-ion collider. Sanjin Benić, Davor Horvatić, Abhiram Kaushik, Eric Andreas Vivoda. We compute exclusive ηc production in high energy electron-nucleon and electron-nucleus collisions that is sensitive to the Odderon. In perturbative QCD the Odderon is a C -odd color singlet consisting of at least three t -channel ...The odderon can be seen as the total contribution coming from all types of odd gluon exchange. It represents the involvement of all of three, five, seven or other odd number numbers of gluons. By contrast, the older model assumes a contribution from all even numbers of gluons, so it includes contributions from two, four, six or more even ...Odderon signal in the comparison of the H (x, s) scaling functions of elastic pp collisions at √ s = 7 . 0 to that of p ¯ p collisions at √ s = 1 . 96 TeV .However, when combining this signal with the Odderon signals from the ReBB model in the 0.37 $\leq -t \leq$ 1.2 GeV$^2$ four-momentum-transfer range at $\sqrt{s} = $ 1.96, 2.76 and 7 TeV, it turns ...Starting from the leading Odderon solution of the three gluon system in perturbative QCD we introduce, as a first step towards the transition to the non-perturbative region, an infrared cutoff and use the running QCD coupling constant. In our numerical analysis we find that the fixed cut solution with intercept one persists, hinting at a physical Odderon with intercept one and a small t-slope.The odderon is defined as a singularity in the complex plane, located at J = 1 when t = 0 and which contributes to the odd crossing amplitude [ 1 , 2 ]. The colorless C -odd 3-gluon state,Starting from a simple empirical parametrization of the scattering amplitude, successfully describing the dip-bump structure of elastic p p 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 p ¯ p and p p elastic and total cross sections.A Swedish-Hungarian research group has discovered mythical particles in experimental data from the Large Hadron Collider at CERN in Switzerland. They identified the Odderon in connection with an advanced data analysis study at the particle accelerator CERN. Roman Pasechnik, particle physics researcher at Lund University, said, "This is a ...An odderon—in theory—is a subatomic quasiparticle, meaning something that behaves enough like a particle to be considered one. First theorized back in 1973, it has eluded observation by ...Sep 6, 2021 · 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. Extracting the Odderon from. and. scattering data. Andras Ster, Laszlo Jenkovszky, Tamas Csorgo. Starting from a simple empirical parametrization of the scattering amplitude, successfully describing the dip-bump structure of elastic scattering in at fixed values of , we construct a toy model interpolating between missing energy gaps to …The U.S. Department of Energy's Office of Scientific and Technical InformationDownload a PDF of the paper titled Toward the existence of odderon as a three-gluon bound state, by Hua-Xing Chen and 1 other authors Download PDF Abstract: 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 ...The odderon remains an elusive object, 33 years after its invention. The odderon is now a fundamental object in QCD and it has to be found experimentally if QCD is right. In the present paper, we ...The idea of the Odderon 1 , the partner of the Pomeron which is odd under parity P and charge conjugation C (like the photon), is related to the possibility that the real part of a scattering amplitude increases with energy as fast as the imaginary part. The scattering amplitude in the complex angular momentum plane possesses a rightmost ...From Sci-News.com, March 19, 2021: Physicists from the TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement) Collaboration at CERN's Large Hadron Collider (LHC) and the DØ Collaboration at Fermilab have found strong new evidence for the odderon, an elusive three-gluon state predicted almost five decades ago.Scaling behaviour of the differential cross section dσ/dt of elastic pp collisions in the ISR energy range of √ s = 23.5−62.5 GeV. The measured differential cross section data are taken from ...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.We describe an analysis comparing the pp[over ¯] elastic cross sectionApr 13, 2021 · Scientists predicted the exist Here \(\Phi \) is the complex pomeron field, \(\Psi \) is the complex odderon field, \(\Phi ^{+}\) and \(\Psi ^{+}\) are their conjugates, \(\mu _P\) and \(\mu _O\) are the pomeron and odderon mass parameters equal to the intercepts minus 1, respectively, the effective coupling constant \(\lambda \) is the same as in the pure pomeron theory ().To take the odderon signature into account its ... The recent TOTEM data [] for the parameter \(\rho \), whi Odderon 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 ...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: 2.2.. Evolution equationIt is now straightforward

In December 2020, the D0 and TOTEM Collaborations made public the odderon discovery based on a purely data driven approach in a CERN and Fermilab approved preprint that was later published in Physical Review Letters. In this experimental observation, the TOTEM proton-proton data in the region of the diffractive minimum and maximum was …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 ...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 ...An alternative to probe the Odderon is the exclusive $\eta_c$ photoproduction in hadronic collisions. As the Pomeron exchange cannot contribute to this process, its observation would indicate the ...part contains the Odderon and a contribution from the ω Reggeon. A direct way to "see" the Odderon in the data is to compare the differential cross-section of in elastic pp and pp¯ scattering at TeV energies [15, 16] since at suf-ficiently high √ s the Reggeon contributions decrease be-low the experimental errors. In this case, the ...

Surprisingly, notable qualitative differences in B(t) for pp and for p p ¯ collisions point towards an Odderon effect. As a by-product, we clearly identify the proton substructure with two different sizes at the ISR and LHC energies, that has striking similarity to a dressed quark (at the ISR) and a dressed diquark (at the LHC). 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 ...For the odderon-exchange process we shall use the ansätze from [9] and we shall try to get information on the odderon parameters and couplings from the comparison to the WA102 data for the → ...…
