Alpha-Core Breakup in the Strong Decay of \({}_{ΛΛ}^{6}\mathrm{He}\) to a Deeply Bound \(H\) Dibaryon
Mahboubeh Shahrbaf, Makoto Oka
We investigate the effect of -core breakup on the strong conversion of \({}^{6}_{ΛΛ}\mathrm{He}\) into a deeply bound \(H\) dibaryon. In addition to the coherent \(H+{}^{4}\math…
Hyperonic Softening versus Nucleonic Three-Body Repulsion in Hypernuclear Matter within a microscopic approach
Mahboubeh Shahrbaf
We investigate cold homogeneous matter composed of neutrons, protons, and hyperons within our hyperonic extension of the lowest-order constrained variational (LOCV) method, her…
Probing Strange Dark Matter through -mode Oscillations of Neutron Stars with Hyperons and Quark Matter
Mahboubeh Shahrbaf, Prashant Thakur, Davood Rafiei Karkevandi
We investigate the impact of a hypothetical bosonic dark matter (DM) candidate, the sexaquark, on the fundamental (-mode) oscillations of neutron stars (NSs). By varying the DM…
Hyperons in Neutron Stars across the observed mass range: Insights from realistic -N and - interactions within a Microscopic Framework
Ali Mohammad Ali Looee, Mahboubeh Shahrbaf, Hamid Reza Moshfegh
We investigate the equation of state (EOS) and macroscopic properties of neutron stars (NSs) and hyperonic stars within the framework of the lowest order constrained variational (L…
Exploring the distribution and impact of bosonic dark matter in neutron stars
Davood Rafiei Karkevandi, Mahboubeh Shahrbaf, Soroush Shakeri +1
The presence of dark matter (DM) within neutron stars (NSs) can be introduced by different accumulation scenarios in which DM and baryonic matter (BM) may interact only through the…
Observational Probes of the Neutron Star Equation of State with Hyperons, Bosonic Dark Matter, and Quark Matter
Mahboubeh Shahrbaf, Davood Rafiei Karkevandi, Alexander Ayriyan +1
Context. The presence of dark matter in neutron stars is of growing interest due to its potential impact on the structure and observable properties of these objects. Among the vari…
A Crossover phase transition based on the phenomenology of hadronic matter and quark matter
Mahboubeh Shahrbaf
The phase transition calculations are utilized for an in-depth understanding of the thermodynamics of the deconfinement transition to perform the best analysis of the QCD phase dia…
Special point "trains" in the M-R diagram of hybrid stars
David Blaschke, Alexander Ayriyan, Mateusz Cierniak +3
We present a systematic investigation of the possible locations for the special point (SP), a unique feature of hybrid neutron stars in the mass-radius diagram. The study is perfor…
Sexaquark dilemma in neutron stars and its solution by quark deconfinement
M. Shahrbaf, D. Blaschke, S. Typel +2
Following the idea that a stable sexaquark state with quark content (uuddss) would have gone unnoticed by experiment so far and that such a particle would be a good dark matter can…
Quark deconfinement in compact stars through sexaquark condensation
D. Blaschke, O. Ivanytskyi, M. Shahrbaf
In this contribution, we present for the first time a scenario according to which early quark deconfinement in compact stars is triggered by the Bose-Einstein condensation (BEC) of…
Constraining free parameters of a color superconducting non-local Nambu-Jona-Lasinio model using Bayesian analysis of neutron stars mass and radius measurements
Mahboubeh Shahrbaf, Sofija Antić, A. Ayriyan +2
We provide a systematic study of hybrid neutron star equations of state (EoS) consisting of a relativistic density functional for the hadronic phase and a covariant nonlocal Nambu-…
Mixed phase transition from hypernuclear matter to deconfined quark matter fulfilling mass-radius constraints of neutron stars
M. Shahrbaf, D. Blaschke, S. Khanmohamadi
A recent solution of the hyperon puzzle by a first order phase transition to color superconducting quark matter is revisited in order to replace the Maxwell construction by an inte…
First-order phase transition from hypernuclear matter to deconfined quark matter obeying new constraints from compact star observations
M. Shahrbaf, D. Blaschke, A. G. Grunfeld +1
We reconsider the problem of the hyperon puzzle and its suggested solution by quark deconfinement within the two-phase approach to hybrid compact stars with recently obtained hadro…
