New Anomalous Exchange in Regge Phenomenology and Hard Diffraction

High Energy Physics - Phenomenology 2019-08-17 v2 Nuclear Theory

Abstract

A new mechanism for hard diffraction based on the anomalous f1f_1 trajectory exchange, which we identify as the odd signature partner of the Pomeron, is suggested. We calculate the contribution of the f1f_1 exchange to elastic and dissociative electromagnetic production of vector mesons and show that it gives a dominant contribution to the differential cross sections at large momentum transfers.
