One of the most challenging goals for researchers in the fields of nuclear and particle physics is to better understand the interactions between quarks and gluons — the building blocks of protons and ...

Lattice gauge theory, or lattice QCD, is a calculation method that helps scientists make predictions about the behavior of quarks at low energies. Quarks are particles found inside every atomic ...

Quarks, the basic constituents of much of matter, are so complicated that scientists have been unable to apply fundamental theory to precisely predict the mass of a quark-containing particle. Until ...

"To obtain the difference [g-2], it's necessary to consider all these contributions—both those predicted by QCD [in the Standard Model of particle physics] and others that are smaller but appear in ...

Quarks come in six different 'flavours' and possess a 'colour charge' A collaboration of particle physicists in Europe and North America have calculated the mass of strange quarks to an accuracy of ...
