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 0c→ Ξ - π +. We find α Ξc0 = 0.26±0.18(stat) -0.04+0.05(syst); using the world average value of α Ξ = -0.456±0.014 we obtain α Ξc0 = -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 Ξc0 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.
