Uncertainty Estimation and Anomaly Detection in Chiral Effective Field Theory Studies of Key Nuclear Electroweak Processes

Chiral effective field theory ( \(\chi \) $\chi$ EFT) is a powerful tool for studying electroweak processes in nuclei. I discuss \(\chi \) $\chi$ EFT calculations of three key nuclear electroweak processes: primordial deuterium production, proton–proton fusion, and magnetic dipole excitations of \(^{48}\textrm{Ca}\) ${}^{48}\text{Ca}$ . This article showcases \(\chi \) $\chi$ EFT’s ability to quantify theory uncertainties at the appropriate level of rigor for addressing the different precision demands of these three processes.
