The $\Lambda \Lambda \to YN$ Weak Transition in Double-$\Lambda$ Hypernuclei

K. Sasaki, T. Inoue, M. Oka

We calculate the $\Lambda \Lambda \to YN$ transition rate of ${}_{\Lambda \Lambda }^6$He by the hybrid picture, the $\pi$ and $K$ exchanges plus the direct quark processes. It is found that the hyper…
