NONZERO MASSES OFπ, k, ANDΚMESONS AND ALGEBRAIC REALIZATION OF SU(3) × SU(3) CHIRAL SYMMETRY

摘要

Analyzing a reasonable asymptotic behaviour of the scattering amplitude in the tree graph approximation we consider nonzero masses of pseudoscalar π , K , ηand scalar k mesons in virtual states and we can neglect (in comparison with their energy ШШ→∞) masses of these bosons in initial and final states. All basic relations of ref. /2/ are valid in such approach but besides them new relations arise, from which the parameter c (earlier introduced into the mass operator-is determined).
