Abstract

We describe nucleon-nucleus (NA) and nucleus-nucleus (AA) elastic scattering based on the chiral two-nucleon forces (2NFs) and chiral three-nucleon forces (3NFs), using the standard microscopic framework composed of the Brueckner-Hartree-Fock method (BHF) and the g-matrix folding model. The g-matrix for symmetric nuclear matter is calculated from chiral 2NFs of N³LO and chiral 3NF of N²LO by using the BHF method. For elastic scattering, the optical potentials are calculated by folding chiral g-matrix with projectile and target density. This microscopic framework reproduces the experimental data with no adjustable parameter. Chiral-3NF effects are small for NA scattering, but sizable for AA scattering. Chiral 3NF, mainly originated from the 2π-exchange diagram, makes the folding potentials less attractive and more absorptive.
