On the Multi-Component Pomeron in high energy hadronic interactions
  We consider the phenomenon of regge cut splitting, corresponding to the BFKL pomeron into an infinite sequence of regge-poles, which happens when one takes into account the running of QCD coupling with scale. The first members of this sequence, after adjusting their parameters, can effectively include the nonperturbative part of pomeron, and by this way all pomeron components - soft and hard can be treated in a unique way.
