Effects of $\Lambda \Lambda -\Xi N$ mixing in the decay of $S=-2$ hypernuclei

Jordi Maneu Victoria, Assumpta Parreño, Àngels Ramos

We study the non-mesonic weak decay of the doubly-strange hypernucleus ${}_6^{\Lambda \Lambda }$He within a model which considers the exchange of pseudoscalar and vector mesons. Special attention…
