SINGLE PSEUDOSCALAR MESON PRODUCTION IN DIFFRACTIVE ep SCATTERING

Exclusive pseudoscalar meson production in ep scattering at high energies is a direct probe for a possible “odderon” exchange in soft hadronic processes. Using a simple phenomenological ansatz for the odderon, we demonstrate how it can be separated from the contribution due to photon-photon fusion, and the relevant parameters be measured. Total cross sections and differential distributions are ...

Pseudoscalar and Vector Meson Production in Nn Collisions *

Heavy meson production in nucleon-nucleon collisions is discussed within a meson exchange model of hadronic interactions, paying special attention to the basic dynamics that determine the behavior of the cross sections near the threshold energy. The pp → ppφ reaction is discussed as an example of the production of vector mesons in N N collisions. For the pseudoscalar me-son production, results ...

Odderon and Photon exchange in pseudoscalar meson production

We consider exclusive π production in ep-scattering. At high energies odderon and photon exchange contribute. The photon exchange contribution is evaluated exactly using data for the total virtual photon-proton absorption cross section. The odderon exchange contribution is calculated in nonperturbative QCD, using functional integral techniques and the model of the stochastic vacuum. For the pro...
