Charge dependence of the pion-nucleon coupling constant

open access: yesЯдерна фізика та енергетика, 2015
On the basis of the Yukawa potential we study the pion-nucleon coupling constants for the neutral and charged pions assuming that nuclear forces at low energies are mainly determined by the exchange of virtual pions.

Generative Modeling of Nucleon-Nucleon Interactions

open access: yesPhysical Review Letters
Developing high-precision models of the nuclear force and propagating the associated uncertainties in quantum many-body calculations of nuclei and nuclear matter remain key challenges for ab initio nuclear theory. In the present work we demonstrate that generative machine learning models can construct novel instances of the nucleon-nucleon interaction ...
