EFT for nuclear electroweak currents: Foundations and applications

N. Kaiser (TUM) / H. Krebs (RUB

Enormous progress has been made in the past decades towards a reformulation of nuclear
physics within the well founded and systematically improvable framework of chiral effective field
theory. In this project, we will use this approach to perform detailed derivations of the
electromagnetic and axial nuclear exchange currents and study electroweak reactions in few-
ucleon systems that are accessible by exact numerical ab initio methods. In particular, we will for
the first time construct a regularized version of the electroweak exchange currents that is fully
consistent with the underlying chiral nuclear forces, and apply these in a cornucopia of reactions.
