Bridging nuclear and quark matter equations of state

This paper argues Bayesian methods can combine chiral effective field theory and perturbative QCD predictions to produce a smooth equation of state spanning nuclear to quark matter densities. Without intermediate data, the prior significantly affects the intermediate region. Extensions guided by constraints are discussed.
