The theory work, described in a paper recently published as an Editor's Suggestion in Physical Review Letters (PRL), identifies key patterns that would be proof of the existence of a so - called «critical point» in the transition among different
phases of nuclear matter.
High - speed collisions that heat and compress it can give rise to new
phases of nuclear matter: a vapor and perhaps a solid and a plasma

The
nuclear phase diagram: RHIC sits in the energy «sweet spot» for exploring the transition between ordinary
matter made
of hadrons and the early universe
matter known as quark - gluon plasma.
By tracking the particles that emerge from the fireballs, scientists can learn about
nuclear phase transitions — both the melting and how the quarks and gluons «freeze out» as they did at the dawn
of time to form the visible
matter of today's world.
In low energy RHIC collisions, scientists suspect that while the change in
phase from QGP to ordinary protons / neutrons occurs, both distinct states (QGP and ordinary
nuclear matter) coexist — just like bubbles
of steam and liquid water coexist at the same temperature in a pot
of boiling water.
