Ab initio Calculations of Charge Symmetry Breaking in the Hypernuclei

D Gazda, A Gal - Physical Review Letters, 2016 - APS
We report on ab initio no-core shell model calculations of the mirror Λ hypernuclei H Λ 4 and
He Λ 4, using the Bonn-Jülich leading-order chiral effective field theory hyperon-nucleon …

[HTML][HTML] Revisiting the hypertriton lifetime puzzle

A Pérez-Obiol, D Gazda, E Friedman, A Gal - Physics Letters B, 2020 - Elsevier
Conflicting values of the hypertriton (Λ 3 H) lifetime were extracted in recent relativistic heavy-

Charge symmetry breaking in the A= 4 hypernuclei

D Gazda, A Gal - Nuclear Physics A, 2016 - Elsevier
Charge symmetry breaking (CSB) in the Λ-nucleon strong interaction generates a charge
dependence of Λ separation energies in mirror hypernuclei, which in the case of the A= 4 …

S-shell hypernuclei based on chiral interactions

H Le, J Haidenbauer, UG Meißner, A Nogga - The European Physical …, 2021 - Springer
We generalize the Jacobi no-core shell model (J-NCSM) to study double-strangeness
hypernuclei. All particle conversions in the strangeness S=-1,-2 S=-1,-2 sectors are explicitly …

Charge-symmetry breaking in light hypernuclei based on chiral and similarity renormalization group-evolved interactions

A Nogga - AIP Conference Proceedings, 2019 - pubs.aip.org
We present Λ separation energies for light hypernuclei based on chiral hyperon-nucleon
interactions at leading and nextto-leading order. For the very light systems, the problem can …

bound state and resonance

TY Htun, Y Yan - Physical Review C, 2022 - APS
We perform the ab initio no-core shell model (NCSM) calculation to investigate the bound
state problem of the three-body Λ nn system in chiral next-to-next-to-leading-order NN and …

Effect of a realistic three-body force on the spectra of medium-mass hypernuclei

P Veselý, G De Gregorio, J Pokorný - Physica Scripta, 2018 - iopscience.iop.org
Abstract We adopt the Hartree–Fock method in the proton–neutron-Λ formalism and the
nucleon-Λ Tamm–Dancoff approximation to study the energy spectra of medium-mass …

Charge symmetry breaking in light hypernuclei
