Homing in on the Higgs boson interaction with the charm quark

Since the discovery of the Higgs boson a decade ago, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have been hard at work trying to unlock the secrets of this special particle. In particular, the collaborations ...

Researchers simulate important structural elements of the pion

When it comes to describing the fundamental structure and composition of matter, the research field of quantum chromodynamics (QCD) comes into play. With the help of QCD, the strong interaction—one of the four fundamental ...

Studying the big bang with artificial intelligence

It could hardly be more complicated: tiny particles whir around wildly with extremely high energy, countless interactions occur in the tangled mess of quantum particles, and this results in a state of matter known as "quark-gluon ...

First detection of exotic 'X' particles in quark-gluon plasma

In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons—elementary particles that briefly glommed together in countless combinations before cooling ...

New insight into the internal structure of the proton

While the Large Hadron Collider (LHC) at CERN is well known for smashing protons together, it is actually the quarks and gluons inside the protons—collectively known as partons—that are really interacting. Thus, in order ...

Marathon experiment reveals quirks of quarks

University of Adelaide experts, who are part of the international community of researchers investigating the fundamental physical properties of atoms, may have come across a new paradigm for the way atomic nuclei are built.

Exotic six-quark particle predicted by supercomputers

The predicted existence of an exotic particle made up of six elementary particles known as quarks by RIKEN researchers could deepen our understanding of how quarks combine to form the nuclei of atoms.
