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 ...

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 fundamental structure of the proposed SIMP (strongly interacting massive particle) is similar to that of a pion (left). Pions are composed of an up quark and a down antiquark, with a gluon (g) ...

New result demonstrates the feasibility of the experiment that is designed to study quark confinement: why no quark has ever been found alone. The first experimental result has been published from the ...

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 Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...
