We also show, that this effect increases the widths of the scalar meson decay into two vector ones and state that the decays $χ_{b0,2}\to2J/ψ$ can be used to detect these scalar mesons at Tevatron and LHC colliders.13 pages, 5 figures, error in fig.3 correctedHigh Energy Physics - Phenomenologytext
