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.
