Description
We have measured the proton energy distribution from the 4He(stopped K-,p) reaction by means of time-of-flight. A mono-energetic peak was observed, which is interpreted as the formation of a new kind of neutral tribaryon S0(3115) with isospin T=1 and strangeness S=-1. The mass and width of the state were deduced to be 3117.0-4.4+1.5MeV/c2 and 21MeV/c2, respectively. The state mainly decays into ΣNN
