Does High Energy Behaviour Depend on Quark Masses?
Arguments based on the Renormalization Group invariance indicate the vanishing of hadron scattering amplitudes at infinite energies in massless confined QCD with mass gap in physical spectrum. It is shown also that if at least one quark is massive the RG arguments do not forbid increasing amplitudes...
