30 Dec 1996 | | Journal: | Phys.Rev. C55 (1997) 2196-2213 | | Abstract: | The nonmesonic decay of the hypertriton is calculated based on a hypertriton wavefunction and 3N scattering states, which are rigorous solutions of 3-body Faddeev equations using realistic NN and hyperon-nucleon interactions. The pion-exchange together with heavier meson exchanges for the $Lambda N o N N $ transition is considered. The total nonmesonic decay rate is found to be 0.5% of the free $Lambda$ decay rate. Integrated as well as differential decay rates are given. The p- and n- induced decays are discussed thoroughly and it is shown that the corresponding total rates cannot be measured individually. | | Source: | arXiv, nucl-th/9612065 | | Services: | Forum | Review | PDF | Favorites | |
