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

Strange quark mass dependence of strange quark star properties [PDF]
European 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}} >

Searching for strange quark matter objects among white dwarfs
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 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.

Tidal deformability of strange quark planets and strange dwarfs [PDF]
Physical Review D, 2021 Strange quark matter, which is composed of u, d, and s quarks, could be the true ground of matter. According to this hypothesis, compact stars may actually be strange quark stars, and there may even be stable strange quark dwarfs and strange quark planets.

Repeating fast radio bursts from collapses of the crust of a strange star [PDF]
The 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
Universe, 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.

The strange-quark distribution [PDF]
Zeitschrift für Physik C: Particles and Fields, 1996 We discuss the latest CCFR determination of the strange sea density of the proton. We comment on the differences with a previous, leading--order, result and point out the relevance of quark mass effects and current non--conservation effects. By taking them into account it is possible to solve the residual discrepancy with another determination of the ...

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 ...

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 ...

Boiling of strange-quark matter [PDF]
Physical Review D, 1991 Boiling of strange-quark matter is studied assuming baryon chemical equilibrium between a quark phase described by the bag model, and a hadron phase described by Walecka's mean-field theory. Boiling of quark nuggets at high temperatures is shown to be much less efficient than previously believed. Thus quark nuggets with large baryon numbers may survive
