A Review on Mesonic Decay of Λ Hypernuclei

A review of the present situation of the mesonic decay of A hypernuclei is done. The link between the propagator method and the one with wave functions and nuclear matrix elements is established. The lack of links between the mesonic decay and the nucleon occupation number in nuclear matter is also discussed, as well as the effect of the AN short range repulsion in the mesonic decay of light hypernuclei. The relevance of the 2p2h induced A decay channel is also discussed. Finally an overview of the potential use of the process, when systematic measurements over the periodic table are done, is presented at the end.
