Query: Extraordinary Baryon Fluctuations and the QCD Tricritical Point   The dynamic separation into phases of high and low baryon density in a heavy
ion collision can enhance fluctuations of the net rapidity density of baryons
compared to model expectations. We show how these fluctuations arise and how
they can survive through freezeout.
