Search for the Kaonic Nuclear State, K_s13_s178722_s19pp, in the exclusive pp -> pLambdaK_s16 channel

Abstract

We search for the most basic kaonic nuclear state, K_s13_s178722_s19pp, by studying the exclusive p_s16p_s13_s178594_s19K_s16_s16_s13_s17923_s19_s16p process. Very recently data analysis of the DISTO experiment taken at View the MathML source found a broad peak component in the missing-mass _s13_s17916_s19M(K_s16) and the _s13_s17923_s19p invariant-mass M(_s13_s17923_s19p) spectra, which was enhanced by large-angle emission of protons, and thus assigned to the p_s16p_s13_s178594_s19X_s16K_s16 two-body reaction where X stands for K_s13_s178722_s19pp. We are planning to study the same reaction making use of the SIS-18 synchrotron and the not, vert, similar4_s13_s17960_s19 acceptance FOPI apparatus at the GSI, Darmstadt, Germany at higher beam energies. The experiment is planned to take place in 2009.
