  • Abstract:

    Light nuclear clusters are expected to be ubiquitously present in astrophysical environments and play an important role in different astrophysical phenomena involving ultra-dense baryonic matter, but the estimation of their abundance demands to correctly estimate the in-medium modification of their binding energy. This can be achieved in a phenomenological way, if theoretical models are calibrated to experimental data from heavy-ion collisions in the Fermi energy regime, where these same clusters are produced in comparable density and temperature conditions. The present project aims at building a calibrated low density equation of state via a direct collaboration between theory and experiment . A Bayesian inference (BI) approach will be applied within a relativistic mean field formalism to build a set of equations constrained by observations and experiments for the whole range of densities of interest. A complete equation of state (EoS) appropriate to describe hot neutron stars will be built and made available.
