Abstract
We construct the vertices which describe the emission of closed string particles (pomerons) out of open string states (reggeons). Using those vertices we can construct a ghost-free unified dual model for the amplitude of an arbitrary number of reggeons and pomerons which contains both the conventional Veneziano model and the Shapiro- Virasoro model. The factorization properties of this model are studied in detail. In particular, we extract the reggeon-pomeron direct coupling from the channels where both reggeons and pomerons can be exchanged.Pubblicazioni consigliate
