Recent results on mesonic and non-mesonic weak decays

Recent results from the FINUDA experiment on the Mesonic Weak Decay (MWD) and Non-Mesonic Weak Decay (NMWD) channels of p-shell Λ-hypernuclei are presented and discussed. Magnetic analysis of π−'s from MWD was performed for the first time for , , and ; decay rates were evaluated and a spin-parity assignment JP=3/2+ for ground-state was derived. Spectra of protons from NMWD were obtained for , , , , , , and . An estimation of the contributions of both Final State Interactions (FSI) and two-nucleon induced (2N) decay processes was done, following a model independent approach.
