Abstract
A new mechanism for hard diffraction based on the anomalous trajectory exchange, which we identify as the odd signature partner of the Pomeron, is suggested. We calculate the contribution of the 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.
