New 2024 APS Fellow Jozef Dudek is pursuing theoretical descriptions of exotic hadrons, a yet-untallied group of short-lived subatomic cousins of the proton and neutron, those more familiar atomic ...

Physicists at the Belle experiment at the KEK laboratory in Japan have discovered a new particle that provides the best evidence yet that some mesons contain four quarks rather than the usual two.

Quark recombination in the quark-gluon plasma formed in high-energy nuclei collisions enhances the production of Bc mesons. These mesons consist of a charm quark and a bottom quark. Most of the ...

Scientists at the Department of Energy’s Fermi National Accelerator Laboratory will announce on Friday, June 18 the observation of an unexpected new member of a family of subatomic particles called ...
