“Short-Lived Drops of Early Universe Matter”
Heavy ion colliders, in particular the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory and the Large Hadron Collider (LHC) at CERN, collide heavy particles at relativistic speeds and the energy density reached in the collision rivals that of the early universe. Relativistic heavy ion collisions seek to create in a controlled setting the conditions present in the universe a few microseconds after the big bang. In a brief early moment, the temperature is of the order of trillions Fahrenheit and the fundamental constituents of matter, quarks and gluons, exist as the relevant degrees of freedom rather than bound in protons and neutrons in normal nuclear matter. This hot state of matter, called Quark Gluon Plasma, displays some remarkable properties including near perfect fluidity and extreme opacity. In this seminar I will describe the experimental techniques, how the properties of the plasma are constrained, and connections to other areas of physics.
