Description

New Ideas in Constraining Nuclear Forces

Nuclear forces are the key component in understanding many important physical observables over a wide range of densities, from few-body physics, to nuclear structure, and astrophysical phenomena. A systematic theory for nuclear Hamiltonians is crucial to providing accurate predictions for these systems. In recent years, nuclear physics has benefited greatly from the development of powerful ab initio many-body methods and their combination with interactions from chiral effective field theory. With increasing computational power and continuous development of these methods, we have entered an era of precision nuclear physics. Uncertainties from the nuclear Hamiltonian now dominate over uncertainties from the many-body method.

This workshop aims to bring together specialists in constructing nuclear Hamiltonians and experts in many-body calculations, with the goal of identifying future pathways and novel constraints to improve our understanding of nuclear interactions, which is needed for future high-precision calculations of nuclei and matter from nuclear physics to astrophysics.
