Abstract
As noticed by Fadin, Kuraev and Lipatov in 1975 incorporation of asymptotic freedom into the BFKL equation splits the QCD pomeron into a series of isolated poles in complex angular momentum plane. Following our earlier work on the proton structure function we explore the phenomenological consequences of the emerging BFKL-Regge factorized expansion for the small-x structure function of the pion F2π(x,Q2). We calculate F2π in a small-x region and find good agreement with the recent H1 determination of F2π(x,Q2). We also present the BFKL-Regge factorization based evaluation of the contribution from hard scattering to the observed rise of the NN, πN and real photo-absorption γN and γπ total cross sections.
