• A recent successful observation of a dense and deeply bound \\bar{K} nuclear system, K−pp, in the p + p → K+ + K−pp reaction in a DISTO experiment indicates that the double-\\bar{K} dibaryon, K−K−pp, which was predicted to be a dense nuclear system, can also be formed in p + p collisions. We find theoretically that the K−-K− repulsion plays no significant role in reducing the density and binding energy of K−K−pp and that, when two Λ(1405) resonances are produced simultaneously in a short-range p + p collision, they act as doorways to copious formation of K−K−pp, if and only if K−K−pp is a dense object, as predicted.(Contributed by Toshimitsu YAMAZAKI, M.J.A.)
