2019-04-10 · For this purpose, we employ an effective Lagrangian approach by using the tree-level Born approximation, and various experimental and theoretical inputs. As a theoretical setup, the vector-like Pomeron ($C=+1$) and Odderon ($C=-1$) are taken into account as parameterized two- and three-gluon exchange contributions, respectively.

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 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. 2021-03-22 QCD odderon: Nonlinear evolution in the leading twist Carlos Contreras ,1,* Eugene Levin ,1,2,3,† Rodrigo Meneses,4,‡ and Michael Sanhueza 1,§ 1Departamento de Física, Universidad T´ecnica Federico Santa María, Avenida España 1680, Casilla 110-V, Valparaíso, Chile 2Centro Científico- Tecnológico de Valparaíso, Avenida España 1680, Casilla 110-V, Valparaíso, Chile Ang pomeron ay maiging natanggap noong mga 1960 sa kabila ng katotohanang ang mga nasukat na seksiyong krus ng proton-proton at proton-antiproton na pagkakalat sa mga enerhiyang makukuha nang mga panahong ito ay hindi magkatumbas.

Odderon föreslogs först 1973, men faktiska bevis på dess existens Om ett jämnt antal gluoner byts ut kallas den partikel som skapas av dem en pomeron.

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] . A simple model for elastic diffractive hadron scattering, reproducing the dip-bump structure is used to analyze pp and ¯pp scattering. The main emphasis is on the delicate and non-trivial dynamics in the dip-bump region, near t=−1 GeV2.

While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forwa. The odderon, the counterpart of the pomeron that carries odd charge parity was introduced in 1973 by Leszek Łukaszuk and Basarab Tensor pomeron, vector odderon and diffractive produc- tion of meson and baryon pairs in proton-proton collisions.

The main emphasis is on the delicate and non-trivial dynamics in the dip-bump region, near t=−1 GeV2. The simplicity of the model and the expected smallness of the absorption corrections enables one the control of various contributions to the scattering 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.
