Strangeness in hadronic stellar matter [PDF]
Physical Review C, 1995 We examine the presence of strangeness-bearing components, hyperons and kaons, in dense neutron star matter. Calculations are performed using relativistic mean field models, in which both the baryon-baryon and kaon-baryon interactions are mediated by meson exchange.

Properties of strange quark matter and strange quark stars
European 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.

Theory progress at Strange Quark Matter 2021 [PDF]
EPJ Web of Conferences, 2022 I review recent theory progress reported at the 19th International Conference on Strangeness in Quark Matter (SQM), and discuss open questions to be addressed by the coming editions of SQM.

Quark stars with 2.6 $$M_\odot $$ M ⊙ in a non-minimal geometry-matter coupling theory of gravity
European Physical Journal C: Particles and Fields, 2022 This work analyses the hydrostatic equilibrium configurations of strange stars in a non-minimal geometry-matter coupling (GMC) theory of gravity. Those stars are made of strange quark matter, whose distribution is governed by the MIT equation of state ...

Journal of Physics G: Nuclear and Particle Physics, 1999 Relativistic heavy ion collisions offer the possibility to produce exotic metastable states of nuclear matter containing (roughly) equal number of strangeness compared to the content in baryon number. The reasoning of both their stability and existence, the possible distillation of strangeness necessary for their formation and the chances for their ...

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.

Superbursts from Strange Stars [PDF]
, 2005 Recent models of carbon ignition on accreting neutron stars predict superburst ignition depths that are an order of magnitude larger than observed. We explore a possible solution to this problem, that the compact stars in low mass X-ray binaries that ...

Energy Dependence of Strangeness Production in Heavyion Collision [PDF]
EPJ Web of Conferences, 2022 An experimental overview of the energy dependence of strangeness production is presented. The strange hadrons are considered a good probe to study the QCD matter created in relativistic nucleus-nucleus collisions.

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 ...

, 2009 We perform an O(alpha_s^2) perturbative calculation of the equation of state of cold but dense QCD matter with two massless and one massive quark flavor, finding that perturbation theory converges reasonably well for quark chemical potentials above 1 GeV.
