Momentary Union of the Heaviest Quarks Observed
University of Rochester researchers observed a short-lived union of the heaviest quarks using data from the CMS experiment at CERN.
“The observed quasi-bound state of top and antitop quarks is heavier than the heaviest known atomic nucleus, Oganesson, making it the most compound ever registered,” says physics professor Regina Demina, leader of the University of Rochester research group that conducted the experiment.
“Its discovery deepens our understanding of the strong nuclear force and its ability to bind the fundamental constituents of matter.”
The findings are reported by the Compact Muon Solenoid (CMS) Collaboration at the European Center for Nuclear Research, or CERN. View the report on the CERN website.
