GlueX The spectrometer at Jefferson Lab was used to study the behaviour of gluons within nuclei. (Courtesy: Jefferson Lab/Aileen Devlin) A new experiment has offered the clearest view yet of how ...

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 ...

In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles zinged around at light ...

NEWPORT NEWS, VA – Inside the nucleus of the atom, the building blocks of matter are anything but static. Individual particles are in a constant state of energetic motion, like dancers on a dance ...

Heavy-ion physics is a dynamic field that investigates the behaviour of matter under extreme conditions by colliding nuclei at relativistic speeds. Such collisions create a short-lived, ...

Comparing the number of direct photons emitted when proton spins point in opposite directions (top) with the number emitted when protons collide head-to-tail (bottom) revealed that gluon spins align ...

Scientists have discovered a common thread between the monstrous black holes that lurk at the hearts of galaxies and subatomic glass condensates created in collisions of atomic nuclei. When you ...

Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world's most powerful particle ...

For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons. While the past few decades have produced some compelling candidates, ...

Scientists from the CMS collaboration at CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to understanding how matter behaved in the very early ...

Newly released observations of the top quark -- the heaviest of all known fundamental particles -- could topple the standard model of particle physics. Data from collisions at the Tevatron particle ...
