1. Regge pole n. a pole (pole n.2 13) of a complex function that arises in the scattering of a particle, relating the angular momentum of the incident particle to the scattering amplitude.Such a pole traces a path in the complex angular momentum plane as the energy of the incident particle increases, and represents a (real or virtual) particle exchanged in the interaction.

2. Regge trajectory n. a path traced in the complex angular momentum plane by a Regge pole as the energy of the incident particle varies; (also) a graph (typically an approximate straight line) of the spins of particles against the squares of their rest masses.
