Biagi, S.F. et al.
Properties of the Charmed Strange Baryon c(2460)+ and Evidence for the Charmed Doubly Strange Baryon c at 2.74 GeV/c2
Z. Phys. C28 (1985) 175;

Abstracts
Results are presented from experiment WA62, which searched for charmed strange baryon states produced in --nucleus interactions in the SPS charged hyperon beam at CERN. Properties of the A+ (csu) baryon at 2.46 GeV/c2 are summarized and upper limits are given for decay branching ratios into various channels. Three events observed at 2.74 GeV/c2 in the K + + mass spectrum are interpreted as the first evidence for the T0 baryon with quark content css. Results of a search for the A0 (csd), the isospin partner of the A+, are presented. The results are discussed in the context of current theoretical understanding, and a comparison with other experiments on hadroproduction of charmed baryons is made.
