Search for Strange Sixquark States in PP → K+X Missing Mass Spectra
A new interest to study the S = -1, B = 2 system has recently been raised due to theoretical predictions coming either from both potential  and quark bag model calculations  about the existence of narrow exotic states. In particular the NIJMEGEN GROUP [j] predicts in the MIT bag model a large number of 6 quark configurations with strangeness S = 0, -1 or -2. The stability of these states against quark dissociation or two baryon emission increases with the number of strange quarks involved, the optimum case beeing for the S = -2 system (uu dd ss) that could even present a stable di-hyperon state . No experimental evidence for the observation of such S = -2 states has yet been found, but the cross section level reached in these different experimental researches  does not rule out their existence.
