[en] The problem of reggeization in non-abelian theories has been investigated in many papers. The consistency of high energy behaviour with the reggeization has been confirmed up to 12th perturbative order for the case of degenerate spectrum of vector mesons masses and for particular models with the definite multiplet of scalar mesons chosen. It has been also shown that for arbitrary semi-simple Lie algebra the high energy behaviour - up to 6th perturbative order - is consistent with reggeization provided that the masses of vector mesons are equal. In this talk we would like to present results which go beyond the case of vectors masses degeneracy. We do not assume anything about symmetry group and mechanism of mass generation. Hence we do not assume any conditions on vector masses except those imposed by renormalizability. The problem of reggeization is studied on example of fermion-fermion scattering. We have calculated the scattering amplitude up to 6th order of perturbation theory, in leading log approximation. (author)
