Spectrum of heavy hadrons in QCD with color scalars

A model of quantum chromodynamics with light colored scalars in the arbitrary representation of the gauge group SUc(3) is discussed. Effective scales and limits of the perturbation theory application for e+e- annihilation into hadron in the channels of the quark-antiquark and scalar pair production have been defined. The value of gauge invariant condensate for scalar fields have been found by the order of magnitude from the known value of the quark condensate. On the basis of finite energy QCD sum rules analysis it was concluded that the mass scale and other parameters of new hadrons containing scalars depend on the type of representation according to which the color scalars are transformed
