Towards Phonon-Like Excitations of Instanton Liquid

Abstract

The phonon-like excitations of (anti)-instanton ($\bar{I}I$) 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 ${\Lambda }_{QCD}$, are investigated.
