Phys. Rev. D 71, 051102(R) (2005) [5 pages]Measurement of the α asymmetry parameter for the Ω-→ΛK- Decay
We have measured the α parameter of the Ω-→ΛK- decay using data collected with the HyperCP spectrometer during the 1997 fixed-target run at Fermilab. Analyzing a sample of 0.96×106 Ω-→ΛK-, Λ→pπ- decays, we obtain αΩαΛ=[1.33±0.33(stat)±0.52(syst)]×10-2. With the accepted value of αΛ, αΩ is found to be [2.07±0.51(stat)±0.81(syst)]×10-2. © 2005 The American Physical Society URL:
