Lg. Landsberg, SEARCH FOR EXOTIC-BARYONS WITH THE SPHINX FACILITY, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 107(11), 1994, pp. 2441-2450
In the experiments at the SPHINX facility in the proton beam of the IH
EP accelerator (E(p) = 70 GeV) a number of diffractive production reac
tions were studied. Among them are p + N --> (K+ K- p) + N, p + N -->
(phi p) + N, p + N -->, -->[Lambda(1520) K+] + N, p + N --> [Sigma(138
5)(0) K+] + N, as well as some other processes. The results of the sea
rch for narrow heavy-baryon states, candidates for the cryptoexotic ha
drons with hidden strangeness, are presented.
