What is ab initio in nuclear theory?
A. Ekström, C. Forssén, G. Hagen +3
Ab initio has been used as a label in nuclear theory for over two decades. Its meaning has evolved and broadened over the years. We present our interpretation, briefly review its h…
Posterior predictive distributions of neutron-deuteron cross sections
Sean B. S. Miller, Andreas Ekström, Christian Forssén
We quantify the posterior predictive distributions (PPDs) of elastic neutron-deuteron () scattering cross sections using nucleon-nucleon () interactions from chiral effecti…
Bayesian estimation of the low-energy constants up to fourth order in the nucleon-nucleon sector of chiral effective field theory
Isak Svensson, Andreas Ekström, Christian Forssén
We use Bayesian methods and Hamiltonian Monte Carlo (HMC) sampling to infer the posterior probability density function (PDF) for the low-energy constants (LECs) up to next-to-next-…
Nuclear Forces for Precision Nuclear Physics -- a collection of perspectives
Ingo Tews, Zohreh Davoudi, Andreas Ekström +42
This is a collection of perspective pieces contributed by the participants of the Institute of Nuclear Theory's Program on Nuclear Physics for Precision Nuclear Physics which was h…
Neutron-deuteron scattering cross-sections with chiral interactions using wave-packet continuum discretization
Sean B. S. Miller, Andreas Ekström, Kai Hebeler
In this work we present a framework that allows to solve the Faddeev equations for three-nucleon scattering using the wave-packet continuum-discretization method. We perform system…
