Abstract

Using the ARGUS detector at the e+e storage ring DORIS II at DESY, we have observed parity violation in the decay Λ±cΛπ±. We measure the coefficient of parity violation, αΛc, to be −0.96±0.42. In addition, we measure σ BR (Λ+cΛπ+ and σ BR (Λ+cΣ0π+) to be, respectively, (2.2±0.3±0.4) pb and (2.0±0.7±0.4) pb.

    In Table 2 we summarize the systematic uncertainty for each mode. Several measurements for the modes reported here are present in the literature [12–18]. In Table 3 we present the FOCUS results with a comparison to the PDG values [1].
