Threshold singularities and Gribov's Reggeon calculus

F. Hayot

Research output: Contribution to journalArticlepeer-review


Within the framework of Gribov's Reggeon calculus we study the influence of the two-pion threshold on the Pomeron trajectory. We point out that in order to obtain a physically meaningful result, it is important to know which Reggeon-Reggeon-particle-particle partial-wave amplitudes can be taken to be constants.
