摘要：

In a sample of diffractive events of high multiplicity a sharp five standard deviation signal is observed at M = 2255 MeV/c2 in the K-pπ+ mass distribution and, although with less statistical strength, at the same mass in the Λ0π+π+π- channel. These signals are identified as being due to the decay of the charmed baryon Λ+ c which is produced with a cross section times branching ratio σcB in the range 0.7-1.8 μb for the K-π+p decay and 0.3-0.7 μb for the Λ-π+π+ π- system. © 1979.
