We search for the most fundamental kaonic nuclear state, K-pp by employing the reaction p + p→K+ + X at 3.0 GeV incident beam energy. The experiment makes use of the SIS-18 synchrotron and the ~4π acceptance FOPI apparatus in the cave-B at the GSI, Darmstadt, Germany and aims to collect full kinematics information of the reaction. We look for a signature of the X (≡ K-pp) in both missing mass spectrum by measuring K+, and invariant mass spectrum by measuring decay particles; X → Λ + p. The experiment is planned to take place in 2009.
