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 ...

Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) usually capture what happens when ...

Scientists exploring the dynamic behavior of particles emerging from subatomic smashups at the Relativistic Heavy Ion Collider (RHIC)-a U.S. Department of Energy Office of Science User Facility for ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

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 ...

Trinity's Prof. Stefan Sint, along with collaborators from Germany, Spain and Italy, has published the most precise ...

A team of physicists has embarked on a journey where few others have gone: into the glue that binds atomic nuclei. The resultant measurement, which was extracted from experimental data taken at the ...

"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 ...

Add Yahoo as a preferred source to see more of our stories on Google. For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons ...

For a quarter of a century, physicists have faced a paradox regarding the net spin of protons and neutrons – the spin of their constituent quarks accounts for only a small fraction of their overall ...

An unusual alliance between physicists who study ultrahot plasmas and ultracold atoms is yielding intriguing results – and may even lead to an experimental test for string theory, as Barbara Jacak ...

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 ...
