Schematic phase diagram in the T−μ plane. The lower curve defines the phase transition between confined and deconfined matter for V₁ = 0.01 GeV and G₂ = 0.006 GeV⁴, while the upper one defines the phase transition curve for V₁ = 0.10 GeV and G₂ = 0.016 GeV⁴. The shaded area indicates the region of the FCM parameters considered in this work, 0.01 GeV ≤ V₁ ≤ 0.10 GeV and 0.006 GeV⁴ ≤ G₂ ≤ 0.016 GeV⁴.
