| Abstract: | 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. |
