The strong interaction as a research area encompasses theoretical and experimental studies of the fundamental force described by quantum chromodynamics (QCD), which governs the dynamics of quarks and gluons and the structure of hadrons and nuclei. It includes investigations of color confinement, asymptotic freedom, chiral symmetry breaking, and the phase structure of strongly interacting matter, such as the quark–gluon plasma. Methodologically, it spans perturbative QCD at high energies, lattice QCD and effective field theories at low energies, and phenomenology in high-energy collider, fixed-target, and heavy-ion experiments to test and refine the Standard Model’s strong sector.
Researchers from Kyushu University, Japan have revealed how a special type of force within an atom's nucleus, known as the three-nucleon force, impacts nuclear stability. The study, published in Physics Letters B, provides ...

Chirality is a property of some molecules, subatomic particles, living organisms and other physical or biological systems. This property entails a lack of mirror symmetry in these systems' underlying structures.
In collisions between protons at the Large Hadron Collider (LHC), pairs of top quarks—the heaviest known elementary particles—are frequently produced along with other heavy quarks, including bottom and charm quarks. These ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of ...
