Description
One of the important properties of nuclear forces is
the nuclear repulsive core which provides a stability for atomic nuclei, making
possible the emergence of a structure for the visible matter.
However the origin of the nuclear core is poorly understood. We discuss how
the strong repulsive nuclear core at short distances can emerge from QCD,
even though one should expect a diminishing interaction due to asymptotic freedom.
It is demonstrated that such a repulsion is associated with the non-nucleonic component in
the NN system and we demonstrate how to incorporate non-nucleonic components in the calculation of
nuclear structure at extremely short distances. We also elaborate the approach that the presented
calculations can be extended to infinite nuclear matter at high densities.
