Construction of a Crossing-Simmetric, Regge-Behaved Amplitude for Linearly Rising Trajectories

Alessandra Grieco will present "Construction of a Crossing-Simmetric, Regge-Behaved Amplitude for Linearly Rising Trajectories"  por Gabriele Veneziano (Nuovo Cim.A 57 (1968) 190-197), con el siguiente abstract:

Crossing has been the first ingredient used to make Regge theory a predictive concept in high-energy physics. However, a complete and satisfactory way of imposing crossing and crossed-channel unitarity is still lacking. We can look at the recent investigations on the properties of Reggeization at t ~ 0 as giving a first encouraging set of results along this line of thinking . In this note we propose a quite simple expression for the relativistic scattering amplitude, that obeys the requirements of Regge asymptotics and crossing symmetry in the case of linearly rising trajectories.
