The Simons Foundation has announced a new research collaboration to explore the “glue” that holds the visible matter of the universe together. This team of thirteen principal investigators, led by ...

Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red ...

Holographic QCD employs ideas drawn from string theory and the AdS/CFT correspondence to study the strong coupling regime of quantum chromodynamics, offering a dual gravitational description of quark ...

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 ...

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...
