A view inside a proton moving at nearly the speed of light toward the viewer with its spin pointing horizontally shows differences in the spatial distributions of the momentum of up (left) and down ...

Deeply Virtual Compton Scattering (DVCS) is a key exclusive process in which a highly virtual photon, emitted by an incoming electron, probes a nucleon resulting in the emission of a high‐energy real ...

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 ...

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 ...

While the Large Hadron Collider (LHC) is well known for smashing protons together, it is actually the quarks and gluons inside the protons – collectively known as partons – that are really interacting ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...
