However, at asymptotically high √ s, hadronic cross sections satisfy the unitarity or Froissart bound, σ ≤ π m ln s m where m is the smallest mass in the theory. Thus, the power law growth (1), parametrized by the soft pomeron intercept αP , can be valid only in a preasymptotic, though possibly large, kinematical regime. So far, this growth is not understood in the context of QCD. Indeed, perturbation theory in the LO BFKL framework does result in a powerlike growth
