Recently, strongly bound K nuclear systems have been predicted, which are shown to have large binding energies about 100 MeV for single- K systems and 200 MeV for double- K systems, and consequently they have large nucleon densities. Such systems will open a new paradigm for studying unusual quark-gluon structure in dense, cold and microscopic nuclear systems, in context to chiral symmetry restoration, hadron masses, kaon condensation and strange matter. We present here an experimental program and simulation results to search for the most elementary K cluster system, ppK−, in a p+d @ Tp=4.5GeV reaction with the FOPI apparatus at GSI, which will take place in the middle of next year. This work is supported by GSI.
