Abstract
In an experiment at the CERN intersecting storage rings with √s = 31 GeV, we have measured αP, the product of asymmetry parameter and polarization, for Λ0's and Λ0's produced in pp and pp interactions, respectively. The ratio, (αP)Λ/(αPΛ = −1.04±0.29, is consistent with the value −1, and constitutes the first test of CP invariance in Λ decay.
