Nuclear structure solving problems of fundamental physics

Abstract

Nuclear-structure calculations are important inputs for solving problems of fundamental physics. Such problems are related with, e.g., neutrinos and dark-matter particles and their interactions with atomic nuclei. In this article the focus is directed to the important problem of the renormalization of the weak axial coupling gA and accurate treatment of β spectrum shapes. As particular applications of the spectral shapes the spectrum-shape method (SSM) and the hot topic of “reactor antineutrino anomaly” are introduced.
