Search for the kaonic muclear state, K(-)pp, in the exclusive pp -> p Lambda K+ channel
We search for the most basic kaonic nuclear state, K(-)pp, by studying the exclusive p + p -> K+ Lambda + p process. Very recently data analysis of the DISTO experiment taken at T-p = 2.85 GeV found a broad peak component in the missing-mass Delta M(K+) and the Ap invariant-mass M(Lambda p) spectra, which was enhanced by large-angle emission of protons, and thus assigned to the p+p -> X + K+ two-body reaction where X stands for K(-)pp. We are planning to study the same reaction making use of the SIS-18 synchrotron and the similar to 4 pi acceptance FOP1 apparatus at the GSI, Darmstadt, Germany at higher beam energies. The experiment is planned to take place in 2009.
