Λ- and ΛΛ-hypernuclear decay predictions in a OME model Original Research Article

We present the results of the Meson-Exchange model of Refs. [1,2] for the nonmesonic weak decay of single- and double-Λ hypernuclei. The results shown here include the total nonmesonic (πNM) decay rate, partial decay rates (i. e. decays induced separately by neutrons, πΛn, protons, πΛp, and Λs, πΛΛ), the kinetic energy correlation of np coincidence pairs emitted in the decay of Λ5He, and A, the longitudinal asymmetry in the distribution of final protons coming from the decay of polarized hypernuclei.
