    "abstract": "In this paper we study the modification of the properties of the nucleon in\nthe nucleus within the quark-soliton model. This is a covariant, dynamical\nmodel, which provides a non-linear representation of the spontaneously broken\nSU(2)_L X SU(2)_R symmetry of QCD. The effects of the nuclear medium are\naccounted for by using the Wigner-Seitz approximation and therefore reducing\nthe complex many-body problem to a simpler single-particle problem. We find a\nminimum in the binding energy at finite density, a change in the isoscalar\nnucleon radius and a reduction of the in-medium pion decay constant. The latter\nis consistent with a partial restoration of chiral symmetry at finite density,\nwhich is predicted by other models.",
