Ab initio calculations of Gamow-Teller strength distributions

ORAL

Abstract

The progress in ab initio calculations of atomic nuclei can be attributed to advances in chiral effective field theory, many-body methods, and high-performance computing. In particular, electroweak currents derived from chiral effective field theory have made it possible to accurately calculate corresponding phenomena without quenching factors. These phenomena have wide-ranging implications from nucleosynthesis to neutrinoless double-beta decays. In this presentation, I will detail our recent coupled cluster calculations of Gamow-Teller strength functions in several nuclei where we have utilized interactions and full two-body electroweak currents derived from chiral effective field theory.
