N.O. Agasian , S.M. Fedorov b Institute of Theoretical and Experimental Physics, 117218, Moscow, B.Cheremushkinskaya 25, Russia Abstract. The influence of nonperturbative fields on instantons in quantum chromodynamics is studied. Effective action for instanton is derived in bilocal approximation and it is demonstrated that stochastic background gluon fields… (More)
