Title | Perturbative perspectives for nuclear effective field theories |
Abstract | Effective field theories (EFTs) are broadly recognized as a modern tool to construct nuclear interactions that are compatible with quantum chromodynamics (QCD) as the underlying theory of the strong interaction. While a lot of progress has been made in the development and application of such methods, there remain many important questions to be studied. In this talk, I will present recent calculations that apply perturbation theory to the nuclear few-body problem. I will emphasize the consistent treatment of electromagnetic interactions within an EFT framework, and in particular focus on a new approach that describes light nuclei as emerging from a very simple leading order (the unitarity limit), where -- much like the fine structure of atomic spectra -- observables are moved to their physical values by small perturbative corrections. |
