80. Searching for the QCD critical point using Lee-Yang edge singularities

David Clarke

We present lattice QCD calculations of the position of Lee-Yang edge singularities in the complex chemical potential plane. The singularities have been obtained by the multi-point Pade approach on lattice QCD data of the net baryon number density at imaginary chemical potential. This approach has been used recently to extract the correct scaling of singularities near the Roberge-Weiss...

66. Equilibrium expectations for non-Gaussian fluctuations near a QCD critical point

With the highly anticipated results from the Beam Energy Scan II program at RHIC coming soon, an understanding of particle-number fluctuations and their significance as a potential signature of a possible QCD critical point is crucial. Early works that embarked on this endeavor sought to estimate the fluctuations due to the presence of a critical point assuming they stay in equilibrium [1,2]....

74. Dynamics and freeze-out of non-Gaussian fluctuations of hydrodynamic densities

Maneesha Sushama Pradeep (University of Illinois at Chicago)

The traditional Cooper-Frye freeze-out procedure becomes inadequate in heavy ion collisions that pass near a critical point, where fluctuations in the hydrodynamic densities (not just the mean densities) must be passed faithfully from the fluctuating fluid before freeze-out to the fluctuating particles after. Furthermore, the dynamics of the fluctuations must be computed, since because of...
