From Sci-News.com, March 19, 2021: Physicists from the TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement) Collaboration at CERN’s Large Hadron Collider (LHC) and the DØ Collaboration at Fermilab have found strong new evidence for the odderon, an elusive three-gluon state predicted almost five decades ago.

From the CERN Courier, March 9, 2021: The discovery of an odderon, predicted to exist almost 50 years ago, was the result of a collaboration between CERN and Fermilab using data from the Large Hadron Collider as well as Fermilab’s DZero experiment. The results were presented at a CERN physics talk and are reported in a joint publication on the observations that were made in December 2020.
