PHONONLIKE EXCITATIONS OF INSTANTON LIQUID AND NEW SCALE OF NON-PERTURBATIVE QCD

The phonon-like excitations of (anti)-instanton (ĪI) liquid due to adiabatic variations of vacuum wave functions are studied in this paper. The kinetic energy term is found and the proper effective Lagrangian for such excitations is evaluated. The properties of their spectrum, while corresponding masses are defined by ΛQCD,are investigated.
