Shortly following the Big Bang, the Universe was filled with a chaotic primordial soup of quarks and gluons, particles which are now trapped inside of protons and neutrons. Study of this quark-gluon plasma requires the use ...

Over the past few days, the SPS has been accelerating argon ions, which have started to be sent to the NA61/SHINE experiment. This operating mode, using a new type of ion, required a number of modifications to the accelerator.

When particles collide inside Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC), they melt at trillion-degree temperatures and form a friction-free "perfect" liquid. This quark-gluon plasma, composed of the liberated ...

The nucleus of an atom is composed of protons and neutrons, which are themselves made up of elementary particles called quarks and gluons. Observing these elementary particles is difficult and typically involves smashing ...

For people who study such tiny objects as protons, neutrons, quarks, and gluons, particle physicists do things big. They belong to teams of collaborators that comprise hundreds; they work in laboratories that extend for miles; ...

Protons to the right, ions to the left: the basic principle of proton-ion collisions at the LHC might seem straightforward. However, this is an almost unprecedented mode of collider operation, certainly unique at the energy ...

Scientists have found a way to "see" inside deuterons, the simplest atomic nuclei, to better understand the "glue" that holds the building blocks of matter together. The new results come from collisions of photons (particles ...

In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.
