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

Abstract

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.
