The protons and neutrons of atomic nuclei are themselves constructed of quarks held together by gluons. That quark-gluon relationship is governed by the strong interaction, one of the four elemental ...

Since the 1970s, the Standard Model of Physics has served as the basis from which particle physics are investigated. Both experimentalists and theoretical physicists have tested the Standard Model's ...

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 ...

Researchers have used Europe's most powerful high-performance computing (HPC) infrastructure to run new and more precise lattice quantum chromodynamics (lattice QCD) calculations of muons in a ...
