Hyperons: the strange ingredients of the nuclear equation of state

I Vidaña - Proceedings of the Royal Society A …, 2018 - royalsocietypublishing.org
We review the role and properties of hyperons in finite and infinite nuclear systems. In
particular, we present different production mechanisms of hypernuclei, as well as several …

Review of the electric dipole moment of light nuclei

N Yamanaka - International Journal of Modern Physics E, 2017 - World Scientific
In this paper, we summarize the theoretical development on the electric dipole moment
(CEDM) of light nuclei. We first describe the nucleon level CP violation and its …

Bulk viscosity in neutron stars with hyperon cores

DD Ofengeim, ME Gusakov, P Haensel, M Fortin - Physical Review D, 2019 - APS
It is well known that r-mode oscillations of rotating neutron stars may be unstable with
respect to the gravitational wave emission. It is highly unlikely to observe a neutron star with …

[HTML][HTML] Electric dipole moment of the deuteron in the standard model with NN− ΛN− ΣN coupling

N Yamanaka - Nuclear Physics A, 2017 - Elsevier
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 …

Hyperons in finite and infinite nuclear systems

I Vidaña - Universe, 2021 - mdpi.com
In this work, we shortly review the role and properties of hyperons in finite and infinite
nuclear systems such as hypernuclei and neutron stars. Particularly, we describe different …

Nonmesonic weak decay of double- hypernuclei: A microscopic approach

E Bauer, G Garbarino, CA Rodríguez Peña - Physical Review C, 2015 - APS
The nonmesonic weak decay of double-Λ hypernuclei is studied within a microscopic
diagrammatic approach. In addition to the nucleon-induced mechanism, Λ N→ n N and Λ …

Λ N→ NN EFT potentials and hypertriton non-mesonic weak decay

A Pérez-Obiol, DR Entem, A Nogga - Journal of Physics …, 2018 - iopscience.iop.org
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 …

Non-mesonic weak decay of hypernuclei with effective field theory

A Pérez-Obiol, DR Entem, B Juliá-Díaz… - Journal of Physics …, 2014 - iopscience.iop.org
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 …

Effects of mixing in the decay of hypernuclei

J Maneu, A Parreno, A Ramos - Physical Review C, 2018 - APS
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 …

[HTML][HTML] Next-to-leading order effective field theory ΛN→ NN potential in coordinate space

A Pérez-Obiol, DR Entem, B Juliá-Díaz, A Parreño - Nuclear Physics A, 2016 - Elsevier
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 …
