$k_{perp}$ factorization vs. renormalization group: a small-x consistency argument

The consistency of the BFKL equation with the renormalization group is investigated at next-to-leading log-x level.By use of Kt-factorization, it is found that,besides next-to-leading small-x resummation formulae, a leading, x-dependent redefinition of initial quarks and gluons is needed. Its interp...

description The consistency of the BFKL equation with the renormalization group is investigated at next-to-leading log-x level.By use of Kt-factorization, it is found that,besides next-to-leading small-x resummation formulae, a leading, x-dependent redefinition of initial quarks and gluons is needed. Its interpretation and phenomenological relevance are discussed.

Its interpretation and phenomenological relevance are discussed.I investigate, at leading twist level, the consistency of the BFKL equation with the renormalization group, when next-to-leading log- x termss are included in the quark-sea channel of the anomalous dimension matrix. By use of k ⊥ -factorization, I find that, besides next-to-leading small- x resummation formulae, a leading, x -dependent redefinition of initial quarks and gluons is needed. Its interpretation and phenomenological relevance are briefly discussed.hep-ph/9507307CERN-TH-95-119CERN-TH-95-119oai:cds.cern.ch:2847961995-06-07
