Odderon.

In March 2021, the TOTEM collaboration at CERN and the D-Zero collaboration at Fermilab jointly announced the discovery of the "odderon" particle, a color-neutral gluonic state. The purpose of this tutorial is to help teachers present this important discovery to their students. Workshop Tutorial for Teachers. Divide into groups.The odderon coupling in the process π ± p → ρ ± p is considered and it is shownthat at P lab ⋍ 400 GeV/c the odderon contribution dominates.

a t-channel exchanged odderon [34-38], that is predom-inantly a three-gluon glueball of C = −. We refer to Refs. [39-47] and the review [48] for more discussions. Due to these studies, interests in glueballs are reviving recently. Since the above odderon evidence is still in-direct, it is crucial and important to directly study the ...Az Odderon egyébként nem az egyetlen olyan részecske, amely elméleti síkon létezik a standard modellben, de nem sikerült még bizonyítani - több olyat keresnek még, amelyben szintén csak gluonok vannak, és kvarkok nincsenek, és amelyek az elmélet több furcsaságára is rámutatnak. az Odderon felfedezése sok ilyen részecske ...What is the Odderon? The Odderon consists of three gluons. Gluons “glue” the quarks together to “hadrons”, particles that are held together by the strong …

The advent of quantum chromodynamics (QCD) led theorists to predict the existence of the odderon in 1973. Proving its existence has been a major experimental challenge, however, requiring detailed measurements of protons as they glance off one another in high-energy collisions. While most high-energy collisions cause protons to break into their ...of the odderon has been well predicted within the QCD paradigm. In this picture the odderon appears as an object made of three. reggeized gluons ("reggeons") in the d-color state, as opposed to.

An odderon is the hypothetical exchange of an odd number of gluons. Christophe Royon is a Nuclear Physics professor in the KU Department of Physics & Astronomy. "Until now, most models were thinking there was a pair of gluons - always an even number, said Royon. "Now we measure for the first time the higher number of events and properties ...5 Feb 2018 ...

"If those trucks ...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 and which does not depend on t[16, 17]. Hence, the Odderon only contributes to the real part of the scattering amplitude. For an estimate we will use the following formFor the dipole odderon, we confirm and extend the non-linear evolution equations recently proposed by Kovchegov, Szymanowski and Wallon, which couple the evolution of the odderon to that of the ...Comments: 6 pages, 4 figures, a talk presented by P.
