At vanishing densities, the transition between confined hadrons and the quark\u2013gluon plasma is known to be ill-defined\u2014happening across a wide range of temperatures rather than at a specific temperature. But theory predicts that at large densities and moderately high temperatures, a critical point exists, where the \u201cfuzziness\u201d disappears and a clear distinction can be made between the gas-like hadrons and the liquid-like quark\u2013gluon mix [1\u20133].<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Experiments at the Relativistic Heavy Ion Collider give the first hints of a critical point in the hot quark\u2013gluon \u201csoup\u201d that is thought to have pervaded the infant Universe.
