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 ...

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, ...

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 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 ...

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 ...

Philosophical Transactions: Mathematical, Physical and Engineering Sciences, Vol. 359, No. 1779, The Quark Structure of Matter (Feb. 15, 2001), pp. 279-308 (30 pages) Photon structure derives from ...

Top observation CERN’s ATLAS experiment has confirmed that heavy quark–antiquark pairs are created in the collision of lead ions. (Courtesy: CERN/ATLAS Collaboration) Physicists working on the ATLAS ...

When our universe burst into existence approximately 13.8 billion years ago, it initially gave birth to a “primordial soup” composed of a state of matter known as the quark-gluon plasma. This plasma, ...
