1964 Physics Lett. 9 269/1 Mandelstam has given some arguments that moving branching points may appear in a relativistic theory as a result of singularities to the right in the j-plane for particles with spin. These new singularities correspond to the production threshold of resonance states (reggeons) with negative orbital momenta.
1977 P. D. B. Collins Introd. Regge Theory ii. 71 The power behaviour expected from the exchange of a Regge trajectory (sometimes called ‘Reggeon’)..may be contrasted with that from a fixed-spin (elementary) particle.
1998 Physics Lett. B. 419 348 Contributions from gluon interactions..are studied and represented in terms of reggeon exchanges.
2007 Nucl. Physics B. 784 50 The primary reggeon in QCD is not the pomeron, but the reggeized gluon.

1964 Physics Lett. 12 153/2 If this fact is correct it would modify the reggeonic branch points and the elastic scattering asymptotic amplitude.
2000 Physics Lett. B. 477 156/2 Both the gluon and quark impact factors have the same dependence on the reggeonic momenta.
