CERN researchers precisely measure properties of newly discovered all-charm tetraquarks

CERN researchers have precisely measured the properties of newly discovered "All-Charm Tetraquarks" for the first time. These exotic particles, first presented in 2020, are composed of quarks and are now understood to be strongly bound, offering insights into fundamental universe building blocks. The findings from the CMS collaboration at the LHC will be used to test theories about the forces holding protons and neutrons together.
