At extremely high densities, quarks are expected to form pairs, as electrons do in a superconductor. This high-density quark behavior is called color superconductivity. The strength of pairing inside ...

(Phys.org) —While scientists have become increasingly convinced that the Standard Model of particle physics is incomplete, it's still unclear exactly how the Standard Model needs to be extended.

THERE is something the matter with matter. Around the world, several research groups have reported seeing a particle that does not fit comfortably with our standard picture of matter. As if that ...

Newly discovered particles have incited a fierce debate among experts about the correct picture of matter at the quantum scale. In August 2003, an experiment at the KEKB particle accelerator in Japan ...

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 ...
