Evidence of a particle made up of four tightly bound quarks tests physicists’ understanding of the force that holds protons and neutrons together. The particles in a hadron are bound tightly together ...

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 ...
