Abstract

We derive number of relations between quadrupole energy, elastic pressure, and shear force distributions in baryons using the large NcN_c picture of baryons as chiral solitons. The obtained large NcN_c relations are independent of particular dynamics and should hold in any picture in which the baryon is the chiral soliton. One of remarkable qualitative predictions of the soliton picture is the nullification of the tangential forces acting on the radial area element for any tensor polarisation of the baryon. The derived relations provide a powerful tool to check the hypothesis that the baryons are chiral solitons, say using lattice QCD.
