Abstract

Using the CLEO II detector at the Cornell Electron Storage Ring we have measured the Ξ_c⁰ decay asymmetry parameter in the decay Ξ_c⁰→Ξ^-π⁺. We find α_{ξ c}⁰α_Ξ = -0.26±0.18(stat)_-0.04^+0.05(syst); using the world average value of α_Ξ= -0.456±0.014 we obtain a=o=-0.56±0.39(stat)_-0.09^+0.10(syst). The physically allowed range of a decay asymmetry parameter is -1<α<+1. Our result prefers a negative value: α_{ξ c}⁰ is <0.1 at the 90% C.L. The central value occupies the middle of the theoretically expected range but is not yet precise enough to choose between models.

N2 - Using the CLEO II detector at the Cornell Electron Storage Ring we have measured the Ξc0 decay asymmetry parameter in the decay Ξc0→Ξ-π+. We find αξ c0αΞ = -0.26±0.18(stat)-0.04+0.05(syst); using the world average value of αΞ= -0.456±0.014 we obtain a=o=-0.56±0.39(stat)-0.09+0.10(syst). The physically allowed range of a decay asymmetry parameter is -1<α<+1. Our result prefers a negative value: αξ c0 is <0.1 at the 90% C.L. The central value occupies the middle of the theoretically expected range but is not yet precise enough to choose between models.
