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 ...

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 ...

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 ...

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 ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

CERN’s Large Hadron Collider-b (LHCb) experiment presented its latest discovery last week at a meeting of the European Physical Society Conference on High Energy Physics. Meet the double-charm ...

The exotic family of particles known as tetraquarks has a surprising new member. Dubbed T cc +, it’s the first tetraquark to contain two heavy quarks and two light antiquarks, and it’s the ...
