Beschreibung

The ab initio approach in nuclear theory aims to describe nuclei at the finest possible resolution scale while maximizing predictive power, with chiral effective field theory promising a systematic link to low-energy QCD. The predictive power of chiral Hamiltonians depends on the information content of the data entering the calibration of the low-energy constants. High-energy collisions of light ions offer an exciting and largely untapped source of new information in this regard. I will discuss how fast and accurate emulators of coupled cluster predictions for the corresponding operators probed by collider data, from e.g. the recent O+O and Ne+Ne runs, combined with Bayesian inference, let us explore this new source of information to learn about the low-energy constants with quantified uncertainties.
