Abstract: DE.00001 : Constraining Nuclear Symmetry Energy from Converting Neutron Star EoS into HI Collisions*
8:30 AM–8:42 AM
A natural question is whether this behavior is compatible with heavy-ion experimental data. We explore the entire range allowed by the experimentally obtained coefficients to produce a prior distribution for the speed of sound functional using charge constraints compatible with heavy-ion experiments. Only a fraction of the resulting equations of state are causal and stable. By imposing stability and causality, we find in the posterior distribution that a large bump in the speed of sound can further constrain the symmetry energy expansion coefficients.
