Description
We present an equation of state (EOS) that covers both the hadronic sector of the phase diagram as well as the deconfined sector, where quarks and gluons are the relevant degrees of freedom. This is accomplished through a switching function that enables the transition from the van de Waals Hadron Resonance Gas model, which describes the hadronic phase, to the
Einstein-Maxwell-Dilaton Holographic model, which describes the deconfined
phase.
The proposed switching function ensures a smooth transition in the crossover region, while preserving a first-order phase transition for $\mu_B \gtrsim 600$ MeV, where the holographic model predicts a critical point.
Furthermore, the EOS agrees with the state-of-the-art lattice
QCD thermodynamics.
Since this EOS spans a large range of temperatures and chemical potentials, it can be useful as an input in hydrodynamic simulations of heavy ion collisions.
