The updated results of the precise measurements of the processes e + e − → ρ → π + π − , e + e − → ω → π + π − π 0 and e + e − → φ → K 0 L K 0 S performed by the CMD-2 collaboration are presented. The update appeared necessary due an overestimate of the integrated luminosity in previous analyses.

A complete proof of the quark Reggeization hypothesis in the leading logarithmic approximation for any quark-gluon inelastic process in the multi-Regge kinematics in all orders of α s is given. First, we show that the multi-Regge form of QCD amplitudes is guarantied if a set of conditions on the Reggeon vertices and the trajectories is fulfilled. Then, we examine these conditions and show that they are satisfied.

The hypothesis of the quark Reggeization is tested by taking the high-energy limit of the two-loop amplitude for quark-gluon scattering which was recently calculated. The limit is compatible with the Reggeization in the leading and the next-to-leading orders and allows the determination of the quark trajectory in the two-loop approximation. The trajectory is presented as an expansion in powers of (D − 4) for the space-time dimension D tending to the physical value D = 4.
