Exploring the Phase Diagram of V-QCD with Neutron Star Mergers

Abstract: Determining the phase structure of Quantum Chromodynamics (QCD) and its Equation of State (EoS) at densities and temperatures realised inside neutron stars and their mergers is a long-standing open problem. I will present a framework for the EoS of dense and hot QCD that describes the deconfinement phase transition between dense baryonic and quark matter phases via the holographic V-QCD model. This model is then used in fully general relativistic hydrodynamic simulations of binary systems that are consistent with the first ever observed neutron star merger event GW170817 and the formation of quark matter and the emitted gravitational wave signal are studied.
