Two independent studies have illuminated unexpected substructures in the fundamental components of all matter. Preliminary results using a novel tagging method could explain the origin of the ...

LOS ALAMOS, N.M., February 24, 2021--A complex high-energy nuclear physics experiment, aiming to measure the contributions of antiquarks to the structure of the proton and neutron, has produced ...

A proton isn't just three quarks and gluons, but a sea of dense particles and antiparticles inside. The more precisely we look at a proton and the greater the energies that we perform deep inelastic ...

Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Can subatomic particles contain four or more quarks and antiquarks? The Standard Model of particle physics says an emphatic “yes”, but for decades after quarks were first postulated in the 1960s, ...

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 ...
