Odderon-Pomeron interference - Lunds universitet
Meanwhile, the more commonly seen quasiparticle made up of an even number of gluons is called a pomeron, after the Soviet theoretical physicist Isaak Pomeranchuk. Abstract 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 =−) 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 While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forward limit t= 0 only the double helicity-flip amplitude ϕ2, dominated by the spin-dependent Odderon, survives. This may affect the extraction of the ρ parameter as well as the total cross section in the LHC energy domain and beyond. Our coupling constants for the Pomeron-odderon-ϕ vertex are taken from an analysis of the WA102 data for the p p → p p ϕ reaction. We show that the odderon-exchange contribution significantly improves the description of the p p azimuthal correlations and the dP t “glueball-filter variable” dependence of ϕ CEP measured by WA102.

Mar 30, 2020 We observe qualitatively different behaviour of the contributions arising from \ gamma -Odderon and Pomeron–Pomeron fusion mechanisms. May 15, 2020 While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forward limit t=0 only the double helicity-flip amplitude to the interference of the Odderon C = , and Pomeron C = + exchange amplitudes in QCD.

Noun . odderon (plural odderons) The hypothetical counterpart of the pomeron, carrying odd charge parity. Translations Holographic Pomeron and Odderon at Strong Coupling Marko Djuri´c Richard C. Brower, Boston University Miguel S. Costa, University of Porto Timothy Raben and Chung-I Tan, Brown University Holograv 2014, Holographic Methods and Applications Monday, August 18, 2014 2021-03-23 · The odderon - so named as it comprises an odd number of subatomic particles called 'gluons' - was found by firing protons at each other in the LHC particle accelerator under the French-Swiss border.
Now, a Swedish-Hungarian research group has discovered the mythical particle with the help of extensive analysis of experimental data from the Large Hadron Collider at CERN in Switzerland. the interference of Pomeron and Odderon exchange amplitudes. We calculate within the framework of. QCD, and in the Born approximation, a forward-. Mar 30, 2020 We observe qualitatively different behaviour of the contributions arising from \ gamma -Odderon and Pomeron–Pomeron fusion mechanisms.

The pomeron is generally believed to be responsible for a wide variety of phenomena, such as elastic scattering, rapidity gaps, and vector meson production. In addition, a CP-odd partner of the pomeron, the odderon, has been postulated from theoretical considerations, but could not yet be established experimentally. 2021-03-19 · When it’s an even-numbered group of gluons (two, four, etc.), we call it a pomeron. When the number of gluons in the group is odd (three, five, etc.), well, you guessed it: That’s an odderon. The Pomeron and Odderon ideas have stuck around, and scientists have previously found experimental evidence for the Pomeron, but not the Odderon.
A glimmer of hope. Though QCD predicts the existence of both these effects, scientists have only found experimental evidence for the Pomeron effect. 2021-03-23 · The Odderon particle is what briefly forms when protons collide in high-energy collisions, and in some cases do not shatter, but bounce off one another and scatter. Protons are made up of quarks and gluons, that briefly form Odderon and Pomeron particles.
QCD describes the Pomeron as protons exchanging an
The odderon takes its name from the fact that it appears as an odd-number of gluons moving together. Meanwhile, the more commonly seen quasiparticle made up of an even number of gluons is called a
If that number is even, it's the work of a pomeron quasiparticle; the other option – which seems to happen much less often – is an odderon quasiparticle, a compound with an odd number of gluons.

Here we show that the dual description associates this with the Neveu-Schwartz (B Pomeron and Odderon from TGD point of view. March 2021; DOI: 10.13140/RG.2.2.24551.57764 Pomerons and odderons. At low energies, differences in pp vs pp̄ scattering are due to the exchange of different virtual mesons. At multi-TeV energies, on the other hand, proton interactions are expected to be mediated purely by gluons. Odderon-Pomeron interference.
The first measurements of inclusive densities in midrapidity region are in agreement with these predictions.
A dipole model is used for the pomeron and for the odderon. By construction, our (bare) pomeron ansatz produces a single dip, as observed experimentally. The model reproduces the logarithmically rising cross sections with a unit pomeron Pomeron and odderon exchange can thus explain the energy independence of the asymmetry and predicts that the asymmetry should persist in events with large rapidity gaps. Originalspråk engelska The odderon takes its name from the fact that it appears as an odd-number of gluons moving together, an outcome which would seem to be considerably rarer. Meanwhile, the more commonly seen quasiparticle made up of an even number of gluons is called a pomeron, after the Soviet theoretical physicist Isaak Pomeranchuk. Pomeron and Odderon in terms of Wilson line correlators.
