Program area B
# Program area B - Electroweak interactions and nuclear astrophysics

In research area B, we will investigate consistent electroweak interactions in nuclei and with nuclear matter in astrophysical environments based on the same chiral EFT. This will address the central questions:

How do electroweak interactions couple to nuclei?

How do nuclei, neutrinos, and the equation of state impact the nucleosynthesis in supernovae?

Answering these questions involves understanding the role of two-body currents for electroweak transitions and testing these with electron scattering. We will use electron beams to simulate neutrino reactions and to probe the nuclear structure involved in neutrinoless double-beta decay and in direct detection of dark matter. A particular focus will be on the dipole response of nuclei, which constrains the neutron equation of state. The neutrino reactions, combined with novel calculations of the nuclear matter equation of state for astrophysical applications, will provide a systematic basis to study the nucleosynthesis of elements in core-collapse supernovae.
