N2  - The production of hypernuclei is investigated for p̅+A→Λ‾+ΛA reactions in a covariant meson exchange approach. Besides the conventional pseudo-scalar (K) and vector (K*) channels, we study for the first time also contributions from the correlated πK scalar channel, described by the k/K*0 meson. Initial and final state interactions are considered by eikonal theory. The total and angular differential cross sections of the coherent process p̅+AZ→ΛA(Z−1)+Λ̅ are evaluated at the beam momenta 1:5…20 GeV/c within the meson exchange model with bound proton and Λ-hyperon wave functions. It is shown that the shape of the beam momentum dependence of the hypernucleus production cross sections with various discrete Λ states is strongly sensitive to the presence of the scalar k meson exchange in the p̅p→Λ̅Λ amplitude. This can be used as a clean test of the exchange by scalar πK correlation in coherent p̅A reactions.
