Within this approximation the $<\\alpha_s GG>$-correction to the mixing amplitude can be expressed through the $B$-meson transition form factors at zero momentum transfer. The correction is negative independent of the particular values of the form factors.\n  As a next step, we study these form factors making use of the relativistic dispersion approach based on the constituent quark picture.
