Ab Initio Calculations of Nuclear Masses

Over the past decades, ab initio nuclear calculations have made dramatic progress, reaching even heavy nuclei such as ²⁰⁸Pb. These advancements now allow first-principles calculations of nuclear properties across a wide mass range, including those critical for astrophysics and for probing physics beyond the Standard Model. In this talk, I will first present a conceptual introduction to modern ab initio nuclear theory. I will then focus on recent progress in the development of high-precision chiral nuclear forces and their application to ab initio calculations of nuclear masses.
