Abstract: Ab Initio Nuclear Calculations for Dark Matter-Nucleus and Neutrino-Nucleus Scattering
Over the past decades, ab initio nuclear calculations have made dramatic progress, especially reaching heavy mass nuclei such as 208Pb [1]. This means that it becomes possible to obtain first-principles computation (with quantified uncertainties) of quantities that even reside in the heavy-mass region. The quantities include these relevant for astrophysics and searches for physics beyond the Standard Model. In this talk, I will present a conceptual introduction to modern ab initio nuclear theory. Then, I will focus on recent advances in ab initio calculations of nuclear re- sponses for dark matter-nucleus [2] and neutrino-nucleus elastic and inelastic scattering. Finally, I will present our recent investigation of the ATOMKI anomaly using ongoing proton beam dump neutrino experiments [3].
