A high-statistics determination of the $\Lambda^{0}$ mean lifetime

Recent determinations of the mean lifetime of the Lambda hyperon have given values significantly greater than the previously accepted world average. Using 34000 Lambda to p pi /sup -/ decays in the CERN 2m. hydrogen bubble chamber, we have measured the Lambda lifetime to be (2.611+or-0.020)*10/sup -...

Sumario:Recent determinations of the mean lifetime of the Lambda hyperon have given values significantly greater than the previously accepted world average. Using 34000 Lambda to p pi /sup -/ decays in the CERN 2m. hydrogen bubble chamber, we have measured the Lambda lifetime to be (2.611+or-0.020)*10/sup -10/ sec. (6 refs).
