Electroweak currents from chiral EFT in few-nucleon systems — •Rodric Seutin^1,2,3, Sebastian König^1,3, and Achim Schwenk^1,2,3 — ¹Institut für Kernphysik, Technische Universität Darmstadt — ²Max-Planck-Institut für Kernphysik, Heidelberg — ³ExtreMe Matter Institute EMMI, GSI Helmholtzzentrum für Schwerionenforschung GmbH

Using chiral EFT one is able to construct current operators at the many-body level. As a result of this, it is guaranteed that the current operators can be evaluated consistently with the appropriate nuclear wave functions, obtained as well from chiral interactions. This consistency is a key advantage of the EFT framework. In this talk, we discuss the development of electroweak currents in few-nucleon systems and their applications to electromagnetic form factors as well as electroweak transitions.
