Description

This collection of datafiles contains the different tabulated nuclear equations of state produced through the MUSES Calculation Engine, discussed and used in heavy-ion collisions simulations presented in Studying the QCD Matter produced in Heavy-Ion Collisions using the MUSES Calculation Engine (details about EoS calculation given in the paper) [1].

The MUSES Calculation Engine is a web-based application and workflow management system allowing researchers to run scientific calculations as composable workflows, constructed from a growing library of MUSES modules that calculate equations of state, derive physical observables, and transform data. MUSES is an NSF-funded project to answer critical interdisciplinary questions in nuclear physics, gravitational wave astrophysics, and heavy-ion physics.

The different equation of state tables stored here, together with metadata files describing their content, are: 

  • 4D-TExS from lattice QCD, covering $T \in [0;600]$ MeV with $dT = 2$ MeV and $\mu_{B/Q/S} \in [-800;800]$ MeV with $d\mu_{B/Q/S} = 50$ MeV 
    (see MUSES 4D-TExS module for the code to compute it; when using this table, please cite [2-4])

  • 4D Taylor-expanded lattice QCD, covering $T \in [30;600]$ MeV with $dT = 5$ MeV and $\mu_{B/Q/S} \in [-450;450]$ MeV with $d\mu_{B/Q/S} = 50$ MeV 
    (see MUSES 4D-Taylor module for the code to compute it; when using this table, please cite [5,6])

  • QvdW-HRG + EMD Holography (with critical point at ${\mu_B}_c = 200$ MeV), covering $T \in [0;600]$ MeV with $dT = 1$ MeV and $\mu_{B} \in [0;1000]$ MeV with $d\mu_{B} = 1$ MeV
  • QvdW-HRG + EMD Holography (with critical point at ${\mu_B}_c = 598$ MeV), covering $T \in [0;600]$ MeV with $dT = 1$ MeV and $\mu_{B} \in [0;1000]$ MeV with $d\mu_{B} = 1$ MeV
  • QvdW-HRG + EMD Holography (with critical point at ${\mu_B}_c = 1000$ MeV), covering $T \in [0;600]$ MeV with $dT = 1$ MeV and $\mu_{B} \in [0;1000]$ MeV with $d\mu_{B} = 1$ MeV
    (see MUSES Holographic module and HRG module for the codes used to compute the tables; when using any of these 3 tables, please cite [7-10])
