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 ...

Colliding pairs of copper ions produce significantly more strange quarks per nucleon than pairs of much larger gold atoms. That is the surprising discovery of physicists working on the Relativistic ...

Physicists have announced the discovery of a new type of pentaquark 1. Most ordinary matter is made up of three-quark particles —protons and neutrons. The five-particle pentaquarks and their ...
