Three and two colours finite density QCD at strong coupling: A new look

Simulations in finite density, β=0 lattice QCD by means of the Monomer–Dimer–Polymer algorithm show a signal of first-order transition at finite temporal size. This behaviour agrees with predictions of the mean field approximation, but is difficult to reconcile with infinite mass analytical solution...

Summary:Simulations in finite density, β=0 lattice QCD by means of the Monomer–Dimer–Polymer algorithm show a signal of first-order transition at finite temporal size. This behaviour agrees with predictions of the mean field approximation, but is difficult to reconcile with infinite mass analytical solution. The MDP simulations are considered in detail and severe convergence problems are found for the SU(3) gauge group, in a wide region of chemical potential. Simulations of SU(2) model show discrepancies with MDP results as well.
