Description
Currently at the Beam Energy Scan at RHIC experimental efforts are being made to find the QCD critical point. On the theoretical side, the behavior of higher-order susceptibilities of the net-baryon charge from Lattice QCD may allow us to estimate its position via Taylor expansion of the density of states at $\mu_{B}=0$. However, even if the series expansion continues to higher-orders, there is always the possibility to miss the critical point behavior due to truncation errors. An alternative approach to exploring the QCD critical point is using black hole engineering. This method allows us to obtain susceptibilities fitting the lattice data at $\mu_{B}=0$ and it can be used to calculate observables at extremely large baryonic chemical potentials as well. Additionally, in the black hole engineered EoS there is a clear critical point at $\mu_{B}=725$ MeV and $T=80$ MeV. In this talk, we obtain the freeze-out line and compare it with the hadron resonance gas model, lattice calculations, and experimental data. We also explore higher order fluctuations at the lowest energies at the beam energy scan to see if there are signatures of the critical point.
