Abstract: (Elsevier)
The annihilation rates into hadrons of P-wave heavy quark-antiquark bound states are calculated within SU(3) colour gauge theory (in particular for the charm scheme). An interesting feature we find is a logarithmic divergence for small binding for the states 1 ++ and 1 +− . Implications for the asymptotic freedom approach to the decay rates of the new particles are discussed. An attempt to use quantitatively the obtained results for all the C -even P-waves gives Γ ann (0 ++ ) : Γ ann (2 ++ ) : Γ ann (1 ++ ) ≈ 15 : 4 : 1.- psi mesons: hadronic decay
