strange matter

Strange matter is a particular form of quark matter, usually thought of as a "liquid" of up, down, and strange quarks. It is to be contrasted with nuclear matter, which is a liquid of neutrons and protons (which themselves are built out of up and down quarks), and with non-strange quark matter, which is a quark liquid containing only up and down quarks. At high enough density, strange matter is expected to be color superconducting. Strange matter is hypothesized to occur in the core of neutron stars, or, more speculatively, as isolated droplets that may vary in size from femtometers (strangelets) to kilometers (quark stars).

It looks like not all is going bad for Italian researchers, after the trial of the seismologists: physicists from Italy have discovered the first evidence of a nucleus that doesn’t exist in nature and survives only for 10-10 seconds when created in a laboratory. Strange matter Hypernuclei contain all sorts of protons and neutrons, but […]
