Abstract
A new mechanism for hard diffraction based on the anomalous f(1) trajectory exchange, which we identify as the odd signature partner of the Pomeron, i s suggested. We calculate the contribution of the f(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 larg e momentum transfers.
