Searching for odderon in exclusive vector meson hadroproduction

Abstract

In this talk estimates are presented of the odderon contributions to the exclusive J/psi and Upsilon production cross-sections at the Tevatron and the Large Hadron Collider. The obtained cross-sections are compared to cross-sections of the dominant background subprocesses mediated by the photon exchange. Possible experimental cuts are proposed that reduce the photon background.
