Double $\Lambda$ Hypernuclei and the Nuclear Medium Effective $\Lambda \Lambda$ Interaction

J. Caro, C. Garcia-Recio, J. Nieves

We fit the ${}^1{S}_0\Lambda \Lambda$ interaction in the nuclear medium to the masses of the experimentally known double-$\Lambda$ hypernuclei: ${}_{\Lambda \Lambda }^6$He, ${}_{\Lambda \Lambda }^{10}$Be and ${}_{\Lambda \Lambda }^{13}$…
