Backyard exotica
Article Abstract:
Alford and Jaffe have formulated and performed an important numerical quantum chromodynamics (QCD) experiment. They have studied a slightly modified version of QCD where quark masses are taken to be larger than real-world values.

Hard-core revelations
Article Abstract:
Quantum chromodynamics (QCD) proves that protons and neutrons are built from quarks and gluons and move at the speed of light. These basic particles carry color charges, leading to the additional requirement that they be confined within bags whose contents are overall color-neutral. A landmark discovery demonstrates that hard-core repulsion is a consequence of QCD, thus the strong internucleon force exhibits weak long-range attraction and strong short-range repulsion.

Colour takes the field
Article Abstract:
The phenomenon of colour coherence is a remarkable result, illustrating the unity and predictive power of fundamental physical theories. Electrons and positrons carry electric charge and quarks and antiquarks are their colour counterparts. Gluons are routinely seen as individual particulars but there is a difference between quantum electrodynamics (QED) and quantum chromodynamics (QCD) which leads to different dynamics. QCD predicts that more particles will be produced between quark and antiquark jets when accompanied by a photon, than when they are accompanied by a gluon jet.
