Description
The dibaryonic kaonic nuclear bound state, K-pp is searched by studying an exclusive p+p→p+Λ+K+ process at several beam energies. A signature of the K-pp is explored in a p+p→X(≡K-pp)+K+ reaction that follows a decay of the X into p+Λ. We found in a missing-mass ΔM(K+) spectrum and a Λp invariant-mass M(Λp) spectrum of DISTO data at 2.85 GeV a resonance with M = 2267 MeV/c2 and Γ = 118 MeV. Those events are found to be associated with a mono energetic kaon. We investigate this resonance as a candidate of the K-pp further also with a different beam energies.
