Abstract

Very recently, we have performed a couple of experiments, KEK PS-E549/E570, for the detailed study of the strange tribaryon S⁰ (3115) obtained in KEK PS-E471. In contrast to the previous proton spectrum, no narrow (∼20 MeV) peak structure was found either in the inclusive ⁴He(stoppedK^-, p) or in the semi-inclusive ⁴He(stoppedK^-, p X^±) reaction channel, which is equivalent to the previous E471 event trigger condition. Detailed analysis of the present data and simulation shows that the peak, corresponding to S⁰ (3115), has been an experimental artifact. Present analysis does not exclude the possible existence of a much wider structure.
