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 ...

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...

A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The calculations ...

In this video, we explore the Standard Model of particle physics, detailing the quantum field theories that describe ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's 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 ...

In a paper in Nature, the ALICE Collaboration 1 reports that data from high-energy collisions between protons can be used to investigate the little-understood nuclear forces between protons and ...

Deep within the atoms that make up our bodies and even within the protons and neutrons that make up atomic nuclei, are tiny particles called quarks. When you purchase through links on our site, we may ...

Protons and neutrons, which are collectively known as nucleons, are the building blocks of atomic nuclei and account for more than 99% of the visible matter in the Universe. They are not themselves ...

UPTON, NY—Using some of the world’s most powerful supercomputers, a group of theorists has produced a major advance in the field of nuclear physics—a calculation of the “heavy quark diffusion ...
