摘要
Nuclear saturation is a key property of low-energy nuclear physics thatdepends on fine details of the nuclear interaction. Here we develop a unifiedstatistical framework that uses realistic nuclear forces to link thetheoretical modeling of finite nuclei and infinite nuclear matter. We constructfast and accurate emulators for nuclear-matter observables and employ aniterative history-matching approach to explore and reduce the enormousparameter domain of $\Delta$-full chiral interactions. We find that modelcalibration including \nuc{16}{O} observables gives saturation predictions thatare more accurate and have a smaller variance than those that only use few-bodydata.
