Double-logarithmic asymptotics of quark scattering amplitudes with flavor exchange
Journal Article

· Phys. Rev. D; (United States)
We propose simple equations in terms of the definite-signature partial waves of the quark scattering and annihilation amplitudes with quark-quark and quark-antiquark states in the exchange channel. We discuss the singularities in the complex angular momentum plane generated by the double-logarithmic contributions and point out their relation to the particle Regge trajectories.
