    "abstract": "We have found theoretically that the elementary process, p + p to K+ +\nLambda(1405) + p, which occurs in a short impact parameter (around 0.2 fm) and\nwith a large momentum transfer (Q ~ 1.6 GeV/c), leads to unusually large\nself-trapping of Lambda(1405) by the projectile proton, when a Lambda* -p\nsystem exists as a dense bound state (size ~ 1.0 fm) propagating to K^-pp. The\nseed, called \"Lambda*-p doorway\", is expected to play an important role in the\n(p, K*) type reactions and heavy-ion collisions to produce various Kbar nuclear\nclusters.",
