摘要：
We have measured the proton energy distribution from the He-4(stopped K-, p) reaction by means of time-of-flight. A monoenergetic peak was observed, which is interpreted as the formation of a new kind of neutral tribaryon S-0(3115) with isospin T = 1 and strangeness S = -1. The mass and width of the state were deduced to be 3117.0(-4.4)(+0.5) MeV/c(2) and < 21 MeV/c(2), respectively. The state mainly decays into SigmaNN. (C) 2004 Elsevier B.V. All rights reserved.
