Abstract

We study momentum distributions and short-range correlation probabilities in A=2 and A=3 systems. First, we show results with phenomenological and meson-theoretic two- and three-nucleon forces to verify consistency with previous similar studies. We then apply most recent high-quality chiral nucleon-nucleon potentials up to fifth order in the chiral expansion together with the leading chiral three-nucleon force. The focal points of our investigations are the model dependence of one- and two-body momentum distributions and the impact of three-body forces on them.
