Hadroproduction of Lamda c̳ [arrow] pK[pi]

"Production of the charmed baryon Ac has been observed in n-nucleus collisions at the Proton East area of FNAL. A 50' peak was seen in the decay mode At -+ pK-7r+ (and charge congugate). The lifetime was determined to be consistent with the current world average of 0.23 ps, and the cross section for At at Vi = 33 Ge V was measured to be 0"" BR = 2.1 ± 1.1 (±.74)llb/nucleon for 0.028 < xI < 0.226. The fraction of At / (At + A; ) was estimated to be 78% ± 18%."
