| contents | We propose a novel method to locate the QCD critical point by constructing an expansion along contours of constant entropy density. Applying two independent analysis of lattice QCD data at zero baryon chemical potential, we find a critical point at $T_c = 114 \pm 7$ MeV and $μ_{B_c} = 602 \pm 62$ MeV for an expansion truncated at order $μ_B^2$. This approach is consistent with recent lattice QCD results up to $μ_B/T \leq 3$. A more precise determination of the required expansion coefficients from lattice simulations will be essential for reliably establishing the location of the QCD critical endpoint. |
