Physicists have been chasing a mysterious particle for 50 years—and they may have just found it
X(2370) has long been a leading candidate for a “glueball”—a hypothetical particle made almost entirely of gluons.
High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon ...
New results from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) suggest that gluons, the glue-like particles ...
Combinations of three quarks (RGB) or three antiquarks (CMY) are colorless, as are appropriate combinations of quark/antiquark pairs. The gluon exchanges that keep these entities stable are quite ...
Deep inside atomic nuclei, gluons bind quarks together and help determine the structure of visible matter. A CERN study, with a University of Kansas physicist playing a leading role, has now shown ...
"These results confirm our suspicion that a lot of the gluons' contribution to proton spin comes from the gluons with relatively low momentum," said Ralf Seidl, a physicist from the RIKEN-BNL Research ...
CERN’s ALICE experiment found that gluons behave differently at the smallest scales inside lead nuclei, favoring gluon saturation over a competing shadowing explanation. By measuring J/ψ particle ...
One of the great theoretical challenges facing physicists is understanding how the tiniest elementary particles give rise to most of the mass in the visible universe. A physicist from MIT will talk ...
The PHENIX detector at Brookhaven National Laboratory's Relativistic Heavy Ion Collider records many different particles emerging from RHIC collisions, including photons, electrons, muons, and ...
The three valence quarks of a proton contribute to its spin, but so do the gluons, sea quarks and antiquarks, and orbital angular momentum as well. The electrostatic repulsion and the attractive ...
The discovery of the Higgs boson was rightfully heralded as a triumph of particle physics, one that brought completion to the Standard Model, the collection of theories that describes particles and ...
"These results confirm our suspicion that a lot of the gluons' contribution to proton spin comes from the gluons with relatively low momentum," said Ralf Seidl, a physicist from the RIKEN-BNL Research ...
