OBELIX results on Kaonic Nuclear Clusters production by antiproton annihilation at rest on 4He

Experimental results recently obtained by OBELIX on the possible production of Kaonic Nuclear Clusters by \(\overline{p}\) annihilation on 4He are critically revised and compared with analogous results from experiments with stopped K −. The use of \(\overline{p}\) instead than K − at rest on nuclei in the search of the existence and properties of such objects seems better, both from the experimental side and the discovery potential.
