Weak decay of hypernuclei
The nonmesonic weak decay of L hypernuclei is studied in a shell model framework. A complete strangeness-changing weak LN→NN transition potential, based on one boson exchange, is constructed by including the exchange of the pseudoscalar mesons p , K , h as well as the vector mesons r ,v , and K*, whose weak-coupling constants are obtained from soft meson theorems and SU~6!w . General expression...
متن کاملWeak decay of hypernuclei
The focus of these lectures is on the weak decay modes of hypernuclei, with special attention to Λ–hypernuclei. The subject involves many fields of modern theoretical and experimental physics, from nuclear structure to the fundamental constituents of matter and their interactions. The peculiar behaviour of matter containing strange quarks has raised in recent years many interesting problems, on...
متن کاملDecay of Hypernuclei
We present a nonrelativistic transition potential for the weak strangeness-changing reaction ΛN → NN . The potential is based on a one meson exchange model (OME), where, in addition to the long-ranged pion, the exchange of the pseudoscalar K, η, as well as the vector ρ, ω,K mesons is considered. Results obtained for different hypernuclear decay observables are compared to the available experime...

متن کاملWeak non-mesonic decay of Hypernuclei
We review the mechanism of weak decay of hypernuclei, with emphasis on the non-mesonic decay channels. Various theoretical approaches are discussed and the results are compared with the available experimental data. PACS: 21.80.+a; 13.75.Ev; 25.40.-h
