Abstract
Using the ARGUS detector at the e<sup>+</sup>e<sup>-</sup> storage ring DORIS II at DESY, we have observed parity violation in the decay Λ<sup>±</sup><sub>c</sub> → Λπ<sup>±</sup>. We measure the coefficient of parity violation, α<sub>Λc</sub>, to be −0.96±0.42. In addition, we measure σ BR (Λ<sup>+</sup><sub>c</sub> → Λπ<sup>+</sup> and σ BR (Λ<sup>+</sup><sub>c</sub> → Σ<sup>0</sup>π<sup>+</sup>) to be, respectively, (2.2±0.3±0.4) pb and (2.0±0.7±0.4) pb.
