Description
An investigation of QCD with larger than physical quark masses offers a valuable insight into the physics of deconfinement.
In an effective Polyakov loop model, we show the interplay between the imaginary and real Polyakov loop susceptibility ratio and the baryon number kurtosis. As the quark mass increases, both quantities approach a step-function behaviour. This suggests that the baryon number kurtosis remains an excellent probe of deconfinement even in the large quark mass limit.
We derive the scaling properties of the baryon number cumulants at the deconfinement critical point at zero and non-zero densities. Using the Landau-type potential we extract the mean-field critical exponents and confirm the results with the explicit numerical calculation. We also predict the full critical exponents using the scaling function approach.
