The quarks that make up the nuclei of all atoms around us are known to "mix": the different types of quark occasionally change into one another. The amounts in which these processes happen are not ...

Physicists at Cern have discovered a plethora of new exotic particles being created in the collisions produced by the Large Hadron Collider over the past few years. So many have been found, in fact, ...

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 ...

Protons may have more "charm" than we thought, new research suggests. A proton is one of the subatomic particles that make up the nucleus of an atom. As small as protons are, they are composed of even ...
