Self-gravitating strange dark matter halos around galaxies [PDF]

, 2020
A new family of nonrelativistic, Newtonian, non-quantum equilibrium configurations describing galactic halos is introduced, by considering strange quark matter conglomerates with masses larger than about 8 GeV as new possible components of the dark ...

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 ...

Axion Emission from Strange Matter in Core-Collapse SNe. [PDF]

Physical Review Letters
The duration of the neutrino burst from the supernova event SN 1987A is known to be sensitive to exotic sources of cooling, such as axions radiated from the dense and hot hadronic matter thought to constitute the inner core of the supernova.

Physics of strange matter

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.

Strange Matter: a state before black hole [PDF]

, 2016
Normal baryonic matter inside an evolved massive star can be intensely compressed by gravity after a supernova. General relativity predicts formation of a black hole if the core material is compressed into a singularity, but the real state of such ...

Study of anisotropic strange stars in f(R,T) gravity: An embedding approach under the simplest linear functional of the matter-geometry coupling [PDF]

Physical Review D, 2019
The present work is focused on the investigation of the existence of compact structures describing anisotropic matter distributions within the framework of modified gravity theories, specifically f(R,$\mathcal{T}$) gravity theory.

Strange matter and strange stars in a thermodynamically self-consistent perturbation model with running coupling and running strange quark mass [PDF]

, 2015
A quark model with running coupling and running strange quark mass, which is thermodynamically self-consistent at both high and lower densities, is presented and applied to study properties of strange quark matter and structure of compact stars.

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 ...
