Invited seminar describing the current picture of strongly interacting matter at extreme temperature and baryon density. The talk reviewed how lattice calculations, hydrodynamics, and fluctuation measurements from RHIC map the QCD phase diagram, emphasized ongoing searches for the critical point, and discussed how upcoming experiments can further pin down deconfinement and critical behavior.
Invited seminar delivered to the University of Louisiana at Lafayette Physics Department as part of the Fall 2025 seminar series. The presentation surveyed how high-statistics RHIC measurements, lattice QCD, and dynamical modeling constrain the QCD phase diagram, highlighted signatures of the critical point, and outlined future measurements that will further clarify the properties of strongly interacting matter at extreme densities.
