Search for the K̄NN bound state at LEPS/SPring-8

Research output: Contribution to journalConference articlepeer-review


The KNN bound states were searched for using the photon induced reactions at LEPS/SPring-8. We adopted the d(γ ;K+φ -)X, d(g ;K+)X and d(γ ;K+φ+)X reactions with photon energies from 1.5 - 2.4 GeV to search for the K-pp, K-pn and K-nn bound states. No peak structure corre-sponding to the KNN bound state production was observed in the region from 2.22 to 2.36 GeV=c2 in the inclusive missing mass spectrum of each reaction. The upper limits of the production cross section for the K̄NN bound states were determined.
