Hadroproduction of Lamda c̳ [arrow] pK[pi]
… 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 …

Hadroproduction of Charmed Baryon Lambda ---> Proton, Kaon, Pion
… $\Lambda\sb{\rm c}$ has been observed in n-nucleus collisions at the Proton East area of FNAL. A 5$\sigma$ peak was seen in the decay mode $\Lambda\sbsp{\rm c}{+}$ $\to$ pK$\sp-\pi\sp+$ (and charge congugate). The lifetime was determined to be consistent with the current world average of …

Hadroproduction of D* [right arrow] (K [pi]) [pi]
… has been performed based on data taken from n-nucleus collisions by the experiment E400 at the Proton East area of FNAL. A signal was observed at the 3.3a level that behaves properly under lifetime cuts. A method for determining the acceptance due to spectrometer geometry and analysis cuts was …
