[Prex] Building an Equation of State Density Ladder

[Jay Benesch]

nice review by Jorge and Marc.  One sentence near the end: "we are not aware of any theoretical approach that can simultaneously reproduce both CREX and PREX. "

Building an Equation of State Density Ladder
Marc Salinas, Jorge Piekarewicz

    The confluence of major theoretical, experimental, and observational advances are providing a unique perspective on the equation of state of dense neutron-rich matter -- particularly its symmetry energy -- and its imprint on the mass-radius relation for neutron stars. In this contribution we organize these developments in an equation of state density ladder. Of particular relevance to this discussion is the impact of the various rungs on the equation of state and the identification of possible discrepancies among the various methods. A preliminary analysis identifies a possible tension between laboratory measurements and gravitational-wave detections that could indicate the emergence of a phase transition in the stellar core.
