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 ...

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 ...

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 ...

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

Measurements of the properties of exotic particles called all-charm tetraquarks, reported by the CMS Collaboration at the Large Hadron Collider (LHC), are published in Nature this week. The results ...

Hadrons are composite physical systems consisting of quarks bound together by gluons via the non-Abelian SU(3) color gauge interaction of quantum chromodynamics (QCD). They are color-neutral and fall ...

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 ...

Light and heavy New calculations reveal quark distributions in flavour-asymmetric mesons. (Courtesy: iStock Traffic-Analyzer) The distribution of quarks inside flavour-asymmetric mesons has been ...
