Abstract: In modern collider experiments, scientists collide atomic nuclei going at the
speed of light in order to create large systems of deconfined quarks and
gluons called the quark-gluon plasma (QGP). The scientists try to measure
every particle produced in the collision in order to try to completely
reconstruct the physics of the QGP, the state of our universe a few
microseconds after the Big Bang. By measuring as many particles as possible
per collision in a wide acceptance, scientists can explore multi-particle
correlations, which indicate both prosaic reaction mechanisms (like momentum
conservation) and potentially more exotic (and as yet undiscovered) mechanisms
such as a critical opalescence - a beam-energy localized growth of long-range
correlations signalling the existence of a critical point in the nuclear
matter phase diagram. My two research groups work in two different but related
directions. One group explores these correlations, and their integrals called
the "fluctuations," by analyzing the experimental data collected by the STAR
experiment at RHIC. My other group has been building new large-scale detector
upgrades to improve the data coming from these modern experiments. The status
and outlook of these efforts will be presented.
