Odderon

The authors report an odderon Regge trajectory emerging from a field theoretical Coulomb gauge QCD model for the odd signature J{sup PC} (P = C = -1) glueball states (oddballs). The trajectory intercept is clearly smaller than the pomeron and even the {omega} trajectory's intercept which provides an explanation for the nonobservation of the ....

It also led to the recent discovery of the odderon by the D0 and TOTEM collaborations [5, 7] by comparing the elastic dσ /dt cross sections in pp and in pp collisions at √ s =1.96 TeV ...A search for contributions to the reaction ep → eπ • N * from photon-Odderon fusion in the photoproduction regime at HERA is reported, at an average photon-proton centre-ofmass energy W = 215 GeV. The measurement proceeds via detection of the π • decay photons, a leading neutron from the N * decay, and the scattered electron.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:

These collisions directly relate ...A bstractWe consider the reaction γp → π+π−p at high energies. Our description includes dipion production via the resonances ρ, ω, ρ′ and f2, and via non-resonant mechanisms. The calculation is based on a model of high energy scattering with the exchanges of photon, pomeron, odderon and reggeons. The pomeron and the C = +1 reggeons are described as effective tensor exchanges, the ...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 ...2 Searching for evidence of Odderon exchange Although in QCD we expect both Pomeron and Odderon exchange to contribute to scattering processes, the pre{LHC experimental quest for the Odderon has proven to be quite a challenging task, see for instance [22,24,25,30] for reviews. In particular, the contribution from Odderon

The odderon intercept is calculated directly, from its expression via an average energy of the odderon Hamiltonian, using both trial wave functions in the variational approach and the wave function recently constructed by Janik and Wosiek. The results confirm their reported value for the energy. Variational calculations give energies some 30% ...We find that the odderon amplitude increases as x decreases from 0.1 to 0.01. At yet lower x, the reversal of this energy dependence would reflect the onset of universal small-x renormalization ...The existence of odd charge-conjugation, zero flavor-number exchange contributions to high energy hadron scattering amplitudes is a basic prediction of quantum chromodynamics, following simply from the existence of the color-singlet exchange of three reggeized gluons in the t-channel [1].In Regge theory, the "Odderon" contribution is dual to a sum over C=P=−1 gluonium states in the t ...The numerical results found show that the inclusion of odderon loops enhances the pomeron propagators but somewhat damps the pA amplitudes. In particular, the odderon propagator strongly falls with energy in agreement with conclusions from the QCD. Remarkably the influence of odderon loops is clearly felt both in the propagators and amplitudes.Apr 2, 2019 · 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 smasher, where particles are ...

The effective QCD Hamiltonian, H 3, possesses a number of remarkable properties which allow to solve the odderon problem exactly 3, 10.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. ….

An alternative to probe the Odderon is the exclusive $\eta_c$ photoproduction in hadronic collisions.

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.Secondly, the Odderon has recently been shown to naturally emerge from the Color Glass Condensate (CGC), a theory for the high-energy asymptotics of QCD. It has been argued that saturation/CGC effects tend to decrease the Odderon intercept, possibly providing an explanation for the lack of experimental evidence for the Odderon so far. taft's progressive reforms The TOTEM collaboration at the LHC, in collaboration with the DØ collaboration at the Tevatron collider at Fermilab, have announced the discovery of the odderon - an elusive state of three fundamental particles called gluons that was predicted almost 50 years ago.
