Confronting Strange Stars with Compact-Star Observations and New Physics
Universe, 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 ...

Universe, 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]
EPJ 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 ...

Quark Matter May Not Be Strange [PDF]
Physical Review Letters, 2018 If quark matter is energetically favored over nuclear matter at zero temperature and pressure then it has long been expected to take the form of strange quark matter (SQM), with comparable amounts of $u$, $d$, $s$ quarks. The possibility of quark matter with only $u$, $d$ quarks ($ud$QM) is usually dismissed because of the observed stability of ...

Light- and strange-quark mass dependence of the ρ(770) meson revisited
Journal 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 Quarks and Lattice QCD [PDF]
Few-Body Systems, 2012 The last few years have seen a dramatic improvement in our knowledge of the strange form factors of the nucleon. With regard to the vector from factors the level of agreement between theory and experiment gives us considerable confidence in our ability to calculate with non-perturbative QCD.

The crystallography of strange quark matter [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2006 Cold three-flavor quark matter at large (but not asymptotically large) densities may exist as a crystalline color superconductor. We explore this possibility by calculating the gap parameter Delta and free energy Omega(Delta) for possible crystal structures within a Ginzburg-Landau approximation, evaluating Omega(Delta) to order Delta^6.

Searching for strange quark planets
The Sixteenth Marcel Grossmann Meeting, 2023 Strange quark matter (SQM) may be the true ground state of matter. According to this SQM hypothesis, the observed neutron stars actually should all be strange quark stars. But distinguishing between neutron stars and strange quark stars by means of obser- vations is extremely difficult.

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