• Pomeron as a Reggeized Massive Graviton: (Confinement ). • Kalb-Ramond Field and Odderon :. Sep 18, 2019 Here, we present recent studies for the central exclusive production (CEP) of фф pairs in proton-proton collisions. We consider the pomeron- Strong coupling expansion for the conformal pomeron/odderon trajectories. RC Brower, MS Costa, M Djurić, T Raben, CI Tan. Journal of High Energy Physics 2020年5月15日 from the nonlinear small-x evolution equations. While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forwa.

As in our previous analysis, this part of our program aims at the Odderon∗ Lech Szymanowski† LPT, Universite´ Paris XI, CNRS, Orsay, France, Universite de Lie`ge, Belgium and SINS Warsaw, Poland Abstract We study the exclusive production of J/ψor Υ in ppand pp¯ colli-sions, where the meson emerges from the pomeron–odderon and the pomeron–photon fusion. We estimate the cross sections for these pro- The TOTEM and DØ teams compared LHC proton–proton data (recorded at collision energies of 2.76, 7, 8 and 13 TeV and extrapolated to 1.96 TeV), with Tevatron proton–antiproton data measured at 1.96 TeV, and found evidence again for the odderon.When the teams combined the result with measurements at much smaller scattering angles at 13 TeV by the TOTEM collaboration, the significance of the The U.S. Department of Energy's Office of Scientific and Technical Information to the pomeron and to the odderon, taking into account the anomalous dimensions from some QCD beta functions with dynamical corrections, i.e., considering that the dilatonic ﬁeld became dynamical satisfying the Einstein equations in ﬁve dimensions. Actually, we ﬁrst consider the anomalous Odderon. The odderon, the counterpart of the pomeron that carries odd charge parity was introduced in 1973 by Leszek Łukaszuk and Basarab Nicolescu. Odderons exist in QCD as a compound state of three reggeized gluons. It was potentially observed only in 2017 by the TOTEM experiment at the LHC. BFKL Pomeron or its strong AdS dual the closed string graviton [1].

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 integral cross sections and inclusive densities of secondaries are determined by the Pomeron exchange, and we present the corresponding predictions for them. The first measurements of inclusive densities in midrapidity region are in agreement with these predictions. The possible contribution of Odderon 2016-09-10 · We used a dynamical holographic softwall model to obtain even and odd spin glueball mass spectra and achieved the related Regge trajectories associated with the pomeron and the odderon, respectively. These trajectories are in good agreement with those found in [13] , [17] , [22] , [23] , [27] , [28] , [29] .

At multi-TeV energies, on the other hand, proton interactions are expected to be mediated purely by gluons.

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.

Translations . 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.
