Visiting researcher from PPGFSC / UFSC participates in a research group that finds evidence of Odderon’s evasive particle
Abstract: The professor Roman Pasechnik, visiting professor at the Graduate Program in Physics at UFSC and particle physics researcher at Lund University, he is part of the Swedish-Hungarian research group that discovered the mythical particle Odderon with the help of an extensive analysis of experimental data from the Great Collider of CERN hadrons in Switzerland. For 50 years, the research community has been unsuccessfully searching for this particle.

For 50 years, the research community has been hunting unsuccessfully for the so-called Odderon particle. 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.
In 1973, two French particle physicists found that, according to their calculations, there was a previously unknown quasi-particle. The discovery sparked an international hunt.
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.
And now a research team, involving researchers from Lund University, has succeeded in identifying the Odderon in connection with an advanced data analysis study at the particle accelerator CERN.
“This is a particle physics milestone! It feels fantastic to contribute to an increased understanding of matter; the fundamental building blocks of our world,” says Roman Pasechnik, particle physics researcher at Lund University.
Through extensive data analyzes of elastic proton-proton and proton-antiproton collisions, the researchers were able to hone in on the new particle. The analysis took several months, but finally paid off.
“We worked with some of the world’s best particle physicists. They were astonished when we published our results,” concludes Roman Pasechnik.
