Abstract

New results concerning the detection of p̄d Pontecorvo reactions at rest with hidden and open strangeness in the final state are presented. A very selective 2-prong dedicated trigger has been used to collect a sample of about 8.5 × 10⁶ annihilations. Evidence of the reaction p̄d → φn is shown with a branching ratio of [5.3 ± 0.6(stat.) ± 0.3(syst.)] × 10^-6. Moreover, the reactions p̄d → AK* and p̄d → ΛK⁰ _L have been identified through the reconstruction of the decay Λ⁰ → pπ^-. The preliminary result for the branching ratio is Br(p̄d → Λ⁰K⁰ _L) = [5 ± 1(stat.) ± 2(syst.)] × 10^-7.
