Strangeness in nuclear physics

A Gal, EV Hungerford, DJ Millener - Reviews of Modern Physics, 2016 - APS
Extensions of nuclear physics to the strange sector are reviewed, covering data and models
of Λ and other hypernuclei, multistrange matter, and antikaon bound states and …

Weak decay of Λ-hypernuclei

WM Alberico, G Garbarino - Physics Reports, 2002 - Elsevier
In this review we discuss the present status of strange nuclear physics, with special attention
to the weak decay of Λ-hypernuclei. The models proposed for the evaluation of the Λ decay …

Strangeness nuclear physics: a critical review on selected topics

E Botta, T Bressani, G Garbarino - The European Physical Journal A, 2012 - Springer
Selected topics in strangeness nuclear physics are critically reviewed. This includes
production, structure and weak decay of Λ-Hypernuclei, the ̄ K nuclear interaction and the …

Strangeness-changing rates and hyperonic bulk viscosity in neutron star mergers

MG Alford, A Haber - Physical Review C, 2021 - APS
In this paper, we present a computation of the rates of strangeness-changing processes and
the resultant bulk viscosity in matter at the densities and temperatures typical of neutron star …

Exploring hyperons and hypernuclei with lattice QCD

SR Beane, PF Bedaque, A Parreno… - arXiv preprint nucl-th …, 2003 - arxiv.org
In this work we outline a program for lattice QCD that would provide a first step toward
understanding the strong and weak interactions of strange baryons. The study of …

Dibaryons with strangeness: their weak nonleptonic decay using SU (3) symmetry and how to find them in relativistic heavy-ion collisions

J Schaffner-Bielich, R Mattiello, H Sorge - Physical Review Letters, 2000 - APS
Weak SU (3) symmetry is successfully applied to the weak hadronic decay amplitudes of
octet hyperons. Weak nonmesonic and mesonic decays of various dibaryons with …

Final-state interactions in hypernuclear decay

A Parreno, A Ramos - Physical Review C, 2001 - APS
We present an update of the one-meson-exchange (OME) results for the weak decay of s-
and p-shell hypernuclei [A. Parreño, A. Ramos, and C. Bennhold, Phys. Rev. C 56, 339 …

Weak decay of Λ in nuclei: quarks versus mesons

K Sasaki, T Inoue, M Oka - Nuclear Physics A, 2000 - Elsevier
Decays of Λ in nuclei, non-mesonic modes, are studied by using the ΛN→ NN weak
transition potential derived from the meson exchange mechanism and the direct quark …

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 …

Meson exchange in the weak decay of Λ hypernuclei and the Γn/Γp ratio

D Jido, E Oset, JE Palomar - Nuclear Physics A, 2001 - Elsevier
We take an approach to the Λ nonmesonic weak decay in nuclei based on the exchange of
mesons. The one-pion and one-kaon exchange are considered, together with the exchange …
