We calculate the electric dipole moment (EDM) of the deuteron in the standard model with| Δ S|= 1 interactions by taking into account the NN− Λ N− Σ N channel coupling, which is an …
We consider the Λ N→ NN weak transition, responsible for a large fraction of the nonmesonic weak decay of hypernuclei. We follow the previously derived effective field …

We study to what extent the unique observation of $\Lambda\Lambda $ hypernuclei by their weak decay into known $\Lambda $ hypernuclei, with lifetimes of order 10$^{-10} $ s, rules …
We present a theoretical overview of the developments in hypernuclear weak decay occurred in the last ten years or so, with special emphasis on the one-and two-nucleon …
The potential for the Λ N→ NN weak transition, the main responsible for the non-mesonic weak decay of hypernuclei, has been developed within the framework of effective field …
Abstract The ΛN→ NN interaction, the main responsible for the decay of heavy hypernuclei, is described within the effective field theory (EFT) framework. The EFT is developed up to …
The nonmesonic weak decay of the doubly strange hypernucleus He Λ Λ 6 is studied within a model that considers the exchange of pseudoscalar and vector mesons. Special attention …
The potential in coordinate space for the Λ N→ NN weak transition, which drives the weak decay of most hypernuclei, is derived within the effective field theory formalism up to next-to …
