A supercomputer simulation of the "primordial soup" has revealed that its inner structure is surprisingly complex. When our universe burst into existence approximately 13.8 billion years ago, it ...

Scientists seeking to confirm earlier measurements of the strange quark's contribution to the proton's magnetic moment have found several surprises, instead. CHAMPAIGN, Ill. — Scientists seeking to ...

The strong interaction is one of the fundamental forces of nature, which binds quarks into hadrons such as the proton and the neutron, the building blocks of atoms. According to the quark model, ...

Quark-gluon plasma (QGP) is a state of matter existing at extremely temperatures and densities, such as those that occur in collisions of hadrons (protons, neutrons and mesons). Under so-called ...

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/psi ...

Scientists working at CERN's Large Hadron Collider Beauty (LHCb) experiment announced that they have finally figured out the structure of an exotic particle known as the pentaquark, meaning a group of ...

A new and powerful particle detector just passed a critical test in its goal to decipher the ingredients of the early universe. The sPHENIX detector is the newest experiment at Brookhaven National ...

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet ...

The ALICE collaboration has measured energy–energy correlators of charm-quark jets for the first time, observing the expected ...

Laboratory experiments have recreated the conditions that existed in the early universe before the quarks and gluons created in the big bang had formed the protons and neutrons that make up the world ...
