Abstract
Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the weak decay-asymmetry parameter αΛc in Λc+→Λπ+ decay. Comparing particle with antiparticle decays, we obtain the first measurement of the CP violation parameter A≡αΛc+α Λc/αΛc-αΛc. We obtain αΛc=-0.78±0.16±0.19 and A=-0.07±0.19±0.24 where errors are statistical and systematic. © 2006 Elsevier B.V. All rights reserved.
