Properties of strange quark matter and strange quark stars [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
A Polyakov chiral $$\text {SU(3)}$$ SU(3) quark mean-field (PCQMF) model is applied to study the properties of strange quark matter (SQM) and strange quark star (SQS) in $$\beta $$ β -equilibrium.

Strange quark mass dependence of strange quark star properties [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The effects of strange quark mass on masses, radii, and tidal deformabilities of strange quark stars are studied via the quasiparticle model that includes the non-perturbative features of QCD in low density region. The constraints of $$M_{\mathrm {TOV}} >

Repeating fast radio bursts from collapses of the crust of a strange star [PDF]

open access: yesThe Innovation, 2021
Summary: Strange stars (SSs) are compact objects made of deconfined quarks. It is hard to distinguish SSs from neutron stars as a thin crust composed of normal hadronic matter may exist and obscure the whole surface of the SS.

Gravitational Waves from Strange Star Core–Crust Oscillation

open access: yesUniverse, 2022
According to the strange quark matter hypothesis, pulsars may actually be strange stars composed of self-bound strange quark matter. The normal matter crust of a strange star, unlike that of a normal neutron star, is supported by a strong electric field.

Searching for strange quark matter objects among white dwarfs

open access: yesPhysics Letters B, 2022
The ground state of matter may be strange quark matter (SQM), not hadronic matter. A whole sequence of SQM objects, ranging from strange quark stars and strange quark dwarfs to strange quark planets, can stably exist according to this SQM hypothesis.

Confronting Strange Stars with Compact-Star Observations and New Physics

open access: yesUniverse, 2023
Strange stars ought to exist in the universe according to the strange quark matter hypothesis, which states that matter made of roughly equal numbers of up, down, and strange quarks could be the true ground state of baryonic matter rather than ordinary ...

Role of Quark Matter and Color Superconductivity in the Structure and Tidal Deformability of Strange Dwarfs

open access: yesUniverse, 2023
In 1995, Glendenning, Kettner and Weber postulated the existence of a new class of compact stars resembling white dwarfs but containing a small strange quark-matter core surrounded by hadronic layers attaining much higher densities than those found in ...

Centrality dependence of multistrangeness production in high-energy heavy-ion collisions [PDF]

open access: yesEPJ Web of Conferences, 2022
We compare the experimental data on yields of protons, strange Λ′s, and multistrange baryons (Ξ, Ω), and antibaryons production on nuclear targets, and the experimental ratios of multistrange to strange antibaryon production, at the energy region from ...

Light- and strange-quark mass dependence of the ρ(770) meson revisited

open access: yesJournal of High Energy Physics, 2020
Recent lattice data on ππ-scattering phase shifts in the vector-isovector channel, pseudoscalar meson masses and decay constants for strange-quark masses smaller or equal to the physical value allow us to study the strangeness dependence of these ...

Strange Quark Star (SQS) in Tolman IV potential with density dependent B-parameter and charge

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In this paper, the solutions of Einstein–Maxwell Field Equations for relativistic strange quark star in Tolman-IV potential considering MIT bag model EoS $$p=\frac{1}{3}(\rho -4B)$$ p = 1 3 ( ρ - 4 B ) of interior matter in presence of charge in higher ...
