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 and planned
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 recent
results that describe 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.
