TOWARD THE GROUND STATE IN THE YANG MILLS THEORY

摘要

The excitation spectrum is investigated in the Yano Xills theory in the field ...It is shown, that unstable modes exist in this field and, consequently, the effective action Γ[A] has an imaginary part. Solution of the equationΓ[A]=0 in the class of these fields, as it was in the case of a covariant constant field (directed along one of the axises of isotopic space) can not be stable. Some arquments are brought in favour of the ground state have to be being sought in the class of the field, which have the form ...
