The cross sections and rapidity distributions for these low-lying mesons are analyzed. The Pomeron-Pomeron process was considered relying on a nonperturbative Pomeron model which is justified by the low mass of considered resonances. The associated theoretical uncertainties are discussed.","authors_text":"M.V.T.
