Sumario: | The author investigates the high energy behaviour of a massive non- Abelian gauge theory by deriving a Reggeon field theory. Analysing the leading ln s coefficient in arbitrary order perturbation one finds that due to extensive cancellations between different Feynman diagrams the transverse momentum is always strongly cut off. This leads to the existence of moving Regge poles as leading singularities in all quantum number configurations. A general description is given of the leading ln s piece in arbitrary order perturbation theory and Reggeon trajectory function and triple Reggeon vertices are computed in lowest order. The author finds that the Reggeon belonging to the highest multiplet has a negative mass (intercept above one), and he discusses the possible implication of this result. (13 refs). |
