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, ...

When the quark model was formulated in the 1960s by Murray Gell-Mann and George Zweig, they predicted that mesons (two-quark hadrons) and baryons (three-quark hadrons) would not be the only hadrons in ...

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 ...

Hadrons count among their number the familiar protons and neutrons that make up our atoms, but they are much more than that. In the early 1900s, physicists were trying to find the source of a ...

The Large Hadron Collider (LHC) is also a big hadron discoverer. The atom smasher near Geneva, Switzerland, is most famous for demonstrating the existence of the Higgs boson in 2012, a discovery that ...

Physicists at the European Organization for Nuclear Research (CERN) announced on 5 July that they had observed three exotic new types of particles that had never been seen before—shining a light into ...

An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider (LHC) has now been confirmed by its sister experiment ATLAS. Subscribe to ...

Harry Cliff is a member of the LHCb Collaboration, though he was not directly involved in the work described in this article. Everything you see around you is made up of elementary particles called ...

Scientists working with the Large Hadron Collider (LHC) have discovered three subatomic particles never seen before as they work to unlock the building blocks of the universe, the European nuclear ...
