1 Indications for a critical end point in the phase diagram for hot and dense nuclear matter Roy A. Lacey Stony Brook University Outline Introduction Phase Diagram Search strategy Theoretical guidance Femtoscopic probe Analysis Finite-Size-Scaling Dynamic Finite-Size-Scaling Epilogue Essential message This is the first *significant and quantitative* indication (from the experimental point of view) of the CEP s existence. Anonymous PRL reviewer Roy A. Lacey Phys.Rev.Lett. 114 (2015) 14, Roy A. Lacey, Stony Brook University; Quark Matter 2015, Sept. 28,
2 The QCD Phase Diagram A central goal of the worldwide program in relativistic heavy ion collisions, is to chart the QCD phase diagram Essential Question What new insights do we have on: All are required to fully characterize the CEP & drives the ongoing search Roy A. Lacey, Stony Brook University; Quark Matter 2015, Sept. 28,
3 Theoretical Guidance Dynamic Universality class for the CEP less clear One slow mode z ~ 3 - Model H Son & Stephanov Phys.Rev.

A 20, 4387 (2005) Experimental verification and characterization of the CEP is a crucial ingredient We use femtoscopic measurements to perform our search Roy A. Lacey, Stony Brook University; Quark Matter 2015, Sept. 28,

Reaction trajectories spend a fair amount of time near a soft point in the EOS that coincides with the CEP! Finite-Size Scaling (FSS) is used for further validation of the CEP, as well as to characterize its static and dynamic properties Roy A. Lacey, Stony Brook University; Quark Matter 2015, Sept. 28,

A curse of Finite-Size Effects (FSE)! Only a pseudo-critical point is observed! shifted from the genuine CEP Roy A. Lacey, Stony Brook University; Quark Matter 2015, Sept. 28,

Phys.G 38:085101, 2011 Displacement of pseudo-first-order transition lines and CEP due to finite-size à Finite-size shifts both the pseudo-critical point and the transition line A flawless measurement, sensitive to FSE, can not give the precise location of the CEP Roy A.
