Learn how physicists recreated the early universe’s primordial soup, known as quark-gluon plasma, and discovered how it responds when particles race through it.

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

Scientists at CERN, together with MIT physicists, have found strong evidence that the universe’s first “primordial soup” acted like a liquid. They discovered that when quarks zoom through this plasma, ...

Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon plasma that filled the universe just after the Big Bang really was a ...

Smaller than an atom, but majorly important: introducing the quark! Quarks helped make sense of particle physics, and we'll ...

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, ...

As they probe deeper into the heart of the atom, discovering ever smaller and more mysterious particles and particles within particles, scientists have succeeded in bringing the once stable world of ...

The CMS Collaboration investigated in detail events in which a top quark and an anti‑top quark are produced together in high‑energy proton–proton collisions at √s = 13 TeV, using the full 138 fb⁻¹ ...

Protons may be intrinsically charming. The subatomic particles are a mash-up of three lighter particles called quarks: two of the type known as up quarks and one down quark. But physicists have ...
