The TOTEM collaboration at the LHC, together with the DØ collaboration at the Tevatron collider at Fermilab, have announced the discovery of the odderon – an elusive state of three fundamental particles called gluons that was predicted almost 50 years ago. The result was presented on Friday 5 March during a meeting at CERN, and follows the joint submission in December 2020 of a CERN/Fermilab preprint by TOTEM and DØ reporting the observation. “This result probes the deepest features of the theory of quantum chromodynamics, notably that gluons interact between themselves and that an odd number of gluons are able to be “colourless”, thus shielding the strong interaction,” says TOTEM spokesperson Simone Giani of CERN. “A notable feature of this work is that the results ar

A New Era of Accelerator Science
Even before the Large Hadron Collider (LHC) in Switzerland detected the elusive subatomic particle known as the Higgs boson in 2012, scientists around the world were already hard at work planning for the next particle accelerator. Arguably some of the most sophisticated scientific machines on the planet, these engineering marvels take decades to plan, build, test, and start.
Such is the case for the proposed International Linear Collider, or ILC.
“To fully understand the Higgs particle’s role in nature and go beyond our current theories, we need even more sensitivity and precision, and that’s what the ILC and its experiments are designed to do,” said Jan Strube, a physicist at Pacific Northwest National Laboratory (PNNL). His research pairs advanced computing with high energy physics to optimize the detection capabilities of current and future experiments.
