[en] odderon ; diffractive production ; vector mesons
[en] We study pp and pp collisions which lead to the exclusive production of J/psi or Upsilon from the pomeron-odderon and the pomeron-photon fusion. We calculate scattering amplitudes of these processes in the lowest-order approximation and in the framework of k(perpendicular to) factorization. We present estimates of cross sections for the kinematic conditions of the Tevatron and of the LHC.
