The measurement proceeds via detection of the π 0 decay photons, a leading neutron from the N ∗ decay, and the scattered electron. No π 0 signal is observed and an upper limit on the ...An odderon is a particle that's even odder than its name suggests. It's a particle that isn't really a particle at all, confused yet?

In this paper we extend our recent nonperturbative functional renormalization group analysis of Reggeon field theory to the interactions of Pomeron and Odderon fields. We establish the existence of a fixed point and its universal properties, which exhibits a novel symmetry structure in the space of Odderon-Pomeron interactions. As in our …The odderon appears naturally in perturbative QCD. As one can see from Fig. 1 the QCD odderon describes the exchange of three gluons and all the interactions between them. The QCD odderon has the trajectory with the intercept equal to 1, which does not depend on t [16,17]. Hence, the odderon only contributes to the real part of the scattering ...

Selyugin and others published Odderon, HEGS Model and LHC Data | Find, read and cite all the research you need on ResearchGateTo summarize, we compute sea quark Sivers function in terms of the C-odd part of the dipole amplitude which is identified as spin dependent odderon inside a transversely polarized target. Due to the C-odd nature of odderon, the computed quark Sivers function and anti-quark Sivers function are the same in size, but differ by a minus sign.Considering these results one can conclude that the ReBB model can be used to describe the data at 8 TeV in a limited kinematic region. This limited kinematic region is suitable to perform an Odderon search and to extract an Odderon signal from the 8 TeV pp TOTEM \(d\sigma /dt\) data: As detailed and utilized recently in Refs.

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 ...

We use the DL fit as a frameworkfor comparing different odderon contributions to experimental data. To that end we replace their triple-gluon exchange amplitude by one of the model odderon contributions. We retain the original parameter values of the fit and make no attempt to improve it. 2.2. A position-space modelBy using the model parameters, the Chew-Frautschi plot of the tensor odderon Regge trajectory is evaluated. As a result, the odderon spin-3 mass is predicted to be 3.2 GeV.

In the high energy regime of Quantum Chromodynamics (QCD) novel effective degrees of freedom, reggeized gluons, arise. They form composite states such as the Pomeron (2 reggeized gluons) and Odderon [] (3 reggeized gluons), which are understood within the Balitsky-Fadin-Kuraev-Lipatov (BFKL) approach [].Odderon exchange is described by solving the Bartels-Kwiecinski-Praszalowicz (BKP ...The U.S. Department of Energy's Office of Scientific and Technical Information

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 …Feb 5, 2018 · 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 ... The Odderon is defined as a singularity in the complex j-plane, located at j = 1 when t = 0 and which contributes to the odd-under-crossing amplitude F −.
