Probing the chiral three-nucleon force effects on many-body nuclear reactions

Understanding of the roles of three-nucleon force (3NF) in nuclear few- and many-body systems is one of the fundamental subjects in nuclear physics. Recently, the 3NF is determined by chiral effective field theory in which two-, three-, and many-nucleon forces are treated consistently and systematically. To investigate the roles of a chiral 3NF on many-body nuclear reactions, we construct a microscopic reaction theory based on the g-matrix interaction including the effects of a chiral 3NF. In the framework, the 3NF effects appear through the density dependence of the g-matrix. I show the first investigation of the chiral 3NF effects on nucleus-nucleus elastic and inelastic scattering, and nucleon-knockout reactions.
