ELEMENTARY EXCITATIONS AND DYNAMICAL CORRELATION-FUNCTIONS OF THE CALOGERO-SUTHERLAND MODEL WITH INTERNAL SYMMETRY

We consider the physical properties of elementary excitations of the C alogera-Sutherland (CS) model with SU(K) internal symmetry. From the r esults on the thermodynamics of this model, we obtain the charge, spin , and statistics of elementary excitations. Combining this knowledge a nd the known results on the dynamics iu the spinless and SU(2) CS mode ls, we propose the expressions for the dynamical correlation functions of tile SU(K) CS model. In the asymptotic region, we confirm the cons istency of our results with predictions from conformal field theory.
