NPA Seminar: Jamie Karthein, MIT, “Fluctuations of Conserved Charges for QCD Phase Diagram Characterization”
Fluctuations provide a powerful tool for elucidating the nature of strongly-interacting matter in the QCD phase diagram. In heavy-ion-collision systems, the net-particle number fluctuations are captured at the moment of chemical freeze-out. Studies of the chemical freeze-out via susceptibilities from Lattice QCD and the Hadron Resonance Gas model contribute to the characterization of the transition region of the QCD phase diagram.
