Abstract: (APS)

We report a measurement of Λ polarization in the two-body decay Λc+→Λπ+, in nonresonant e+e− interactions from data taken with the CLEO detector. Using these data we have determined the parity-violating asymmetry decay parameter αΛc to be -1.0−0.0+0.4. We see no evidence for significant Λc+ polarization.
