Description
Hypernuclei offer a unique window on nuclear matter with strangeness and on the role of strange baryons in nuclei. Among them, $\Lambda$-hypernuclei are the most accessible systems and provide an ideal testing ground for these questions. A particularly intriguing question is whether a $\Lambda$ hyperon changes its lifetime once embedded in a nucleus. In this talk, I present a study of mesonic weak decays of light hypernuclei within a non-relativistic cluster effective field theory. In particular, I consider the light systems ${}^4_\Lambda \mathrm{He}$, ${}^4_\Lambda \mathrm{H}$ and ${}^5_\Lambda \mathrm{He}$, focusing on their dominant decay channels and on the role of final-state interactions. The talk will highlight how this framework can help clarify the connection between hypernuclear structure, weak decay, and existing experimental data.
