Decay of Hypernuclei

Abstract

We present a nonrelativistic transition potential for the weak strangeness-changing reaction $\Lambda N\to NN$. The potential is based on a one meson exchange model (OME), where, in addition to the long-ranged pion, the exchange of the pseudoscalar $K,\eta$, as well as the vector $\rho ,\omega ,K^{\ast }$ mesons is considered. Results obtained for different hypernuclear decay observables are compared to the available experimental data.
