New measurement of the Λ lifetime

A new measurement of the Λ lifetime has been performed using three different K^-p experiments in three different hydrogen bubble chambers. The final result based on 36 000 Λ decays leads to a lifetime of (2.626 +- 0.020) x 10^-^1^0 s which is definitely larger than the present accepted value of (2.5...
