DILATONS IN THE TOPOLOGICAL SOLITON MODEL FOR THE HYPERONS

We show that the predicted hyperon masses in the topological soliton m odel are very sensitive to the value to the gluon condensate parameter that appears when the scale invariance and trace anomaly of QCD are t aken into account by introduction of a dilaton field. This contrasts w ith the insensitivity of the soliton properties to the dilaton couplin g. In order that the predicted strange and charmed hyperon spectra agr ee with the empirical ones the gluon condensate parameter has to be ab out (400 MeV)4, which agrees with the result obtained from QCD sum rul es. Within the framework of the present model this implies that the ba g formed by the scalar field must be very shallow.
