Bottomonium particles don't go with the flow

A few millionths of a second after the Big Bang, the universe was so dense and hot that the quarks and gluons that make up protons, neutrons and other hadrons existed freely in what is known as the quark–gluon plasma. The ...

The hunt for hot nuclear matter

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.

STAR detector has a new inner core

For scientists tracking the transformation of protons and neutrons—the components of atomic nuclei that make up everything we see in the universe today—into a soup of fundamental building blocks known quark-gluon plasma, ...

CEBAF turns on the charm

The world's most advanced particle accelerator for investigating the quark structure of the atom's nucleus has just charmed physicists with a new capability. The production of charm quarks in J/ψ (J/psi) particles by CEBAF ...

Physicists reveal why matter dominates universe

Physicists in the College of Arts and Sciences at Syracuse University have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks.
