✦ Synopsis

The weak nomesonic decay of 4-hypernuclei is studied in the context of a one-mesonexchange model. Predictions are made for the decay rate, the pΓ‚n stimulation ratio and the asymmetry in polarized hypernuclear decay.

The physics of the weak decay of hypernuclei is briefly reviewed from a theoretical point of view. Special regard is devoted to the recent progress concerning the determination of the non-mesonic decay widths and the asymmetry parameters. Convincing evidence has been achieved for a solution of the l

We make a careful study about the nonrelativistic reduction of one-meson-exchange models for the nonmesonic weak hypernuclear decay. Starting from a widely accepted effective coupling Hamiltonian involving the exchange of the complete pseudoscalar and vector meson octets (Ο€, Ξ·, K, ρ, Ο‰, K \* ), the
