Abstract: (Elsevier)
The technique of QCD sum rules permitting to calculate trajectories of mesonic Regge poles and their couplings is formulated. It utilises analyticity in momentum transfer t of the moments of the appropriate four-current amplitude for arbitrary values of the moment index n and for large virtualities of the currents. The sum rules relate parameters of Regge poles to the large t part of those moments which are controlled by perturbative QCD and by non-perturbative corrections. A preliminary analysis of the sume rule which gives the ϱ -A 2 - ω -f 0 trajectory is presented.- QUANTUM CHROMODYNAMICS: SUM RULE
