Mar 16, 2021 · In March 2021, the TOTEM collaboration at the LHC, together with the DØ collaboration at the Tevatron collider at Fermilab, announced the discovery of the odderon – an elusive state of three fundamental particles called gluons that was predicted almost 50 years ago. TOTEM LHC experiments. The TOTEM collaboration at the LHC, together with the ... Glueball and oddball resonances lying on the pomeron/odderon trajectories (Chew-Frautchi plot) with threshold and asymptotic behaviour required by analyticity and unitarity are predicted. 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 perturbative QCD odderon exists in two different states. The first one was proposed as the \(C=-1\) eigenstate of the Hamiltonian for three reggeized gluons (the simplest of the series of the so-called BKP states [1,2,3]).Its properties and conformal invariance were discussed very long ago [4, 5].After several attempts to numerically estimate its intercept ("energy") and wave function ...1 Apr 2022 ... 65.5K Likes, 955 Comments.

In the saturation regime, the expectation value of odderon that incorporates multiple gluon exchange effect has been computed in the MV model [1] with a cubic term [27]. The energy dependence of the odderon exchange is described by the BKP equation [28], which also can be formulated in the dipole model [29] and CGC framework [30], [31].3.1 Conformal Pomeron, Odderon and Analyticity At high-energy, analyticity and crossing lead to C = 1 vacuum exchanges, the Pomeron and the Odderon. The qualitative picture for Pomeron exchange in weak coupling [10] has been understood for a long time, in leading order expansion in g 2 YM and all order sum in g YM log(s=s 0). In the conformal ….

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 ...The TOTEM experiment (TOTal Elastic and diffractive cross section Measurement) is one of the nine detector experiments at CERN's Large Hadron Collider.The other eight are: ATLAS, ALICE, CMS, LHCb, LHCf, MoEDAL, FASER and [email protected] shares an interaction point with CMS. The detector aims at measurement of total cross section, elastic scattering, and diffraction processes.The odderon was suggested 50 years ago [1,2] as the C-odd (C ¼ −1) partner of the C-even (C ¼þ1) pomeron in mediating a t-channel colorless exchange in elastic
and to the Odderon interpretation of its decrease with energy (see e.g. Ref. [11, 20]), and hence more care is needed to justify the magnitude and the signi cance of the Odderon e ect in the ˆmeasurement. In o -forward kinematics, a substantiated claim about the Odderon e ect and its signi cance is made recently from the shape analysis of the ...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 ...First we take into account the coupling of the pomeron and odderon on the minimal level, introducing all nonlinear terms different from zero but restricting the partial waves for both ϕ and ψ to l = 0 (that is taking the pomeron at L = 0 and odderon at L = 1) The resulting Pomeron ϕ 0 coupled to odderon ψ 0 and the corresponding gluon density turn out to be practically the same as without ...
john riggins washington redskins We predict glueball/oddball resonances lying on the pomeron/odderon trajectories. A simple new form of the trajectories, with threshold and asymptotic behaviour required by analyticity and unitarity, is proposed. The parameters of these (pomeron and odderon) trajectories are fitted to the data on high-energy elastic proton-proton scattering. The fitted trajectories are extrapolated to the ...In the case of the odderon the wave function in impact-parameter space depends on only one anharmonic ratio and the corresponding functional is signifi- cantly simplified. We discuss in the variational approach the relation between the odderon and the pomeron in QCD. A semi- quantitative argument is given that the intercept of the odderon in ... pyscinfoaryion.con The U.S. Department of Energy's Office of Scientific and Technical InformationDec 21, 2022 · In this work, we propose that the odderon is a reggeized odd-glueball tensor spin-3. To demonstrate our proposal, we study the and elastic scattering by including contributions of the spin-3 odderon and spin-2 pomeron exchange in the process. The phenomenological effective Lagrangian approach is used to calculate the and elastic scattering ... sports management average salary Scientists predicted the existence of the particle, known as the odderon, in 1973, describing it as a rare, short-lived conjointment of three smaller particles known as gluons. Since then, researchers have suspected that the odderon might appear when protons slammed together at extreme speeds, but the precise conditions that would make it ...The U.S. Department of Energy's Office of Scientific and Technical Information kervensdarrin hancockthe co operative principle In the paper we propose and solve analytically the nonlinear evolution equation in the leading twist approximation for the odderon contribution. We found three qualitative features of this solution, which differs the odderon contribution from the Pomeron one: (i) the behavior in the vicinity of the saturation scale cannot be derived from the linear evolution in a dramatic difference with the ... pam keller In perturbative QCD the odderon is a $C$-odd color singlet consisting of at least three $t$-channel gluons exchanged with the target.

These results ... obito sharingan gifmarc cravenlegends field seating chart 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.
