Strange quark matter in a chiral SU(3) quark mean field model [PDF]

open access: yesPhys.Rev. C67 (2003) 015210, 2002
We apply the chiral SU(3) quark mean field model to investigate strange quark matter. The stability of strange quark matter with different strangeness fraction is studied. The interaction between quarks and vector mesons destabilizes the strange quark matter.

Quark, pion and axial condensates in three-flavor finite isospin chiral perturbation theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We calculate the light-quark condensate, the strange-quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory ( $$\chi $$ χ PT) in the presence of an isospin chemical potential at next-to-leading order at

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.

On the estimation of the strange quark mass from the experimental data on the light baryon octet

open access: yesÂderna Fìzika ta Energetika, 2018
Simple relations connecting the strange quark mass to the splittings of the light hyperon masses were obtained on the basis of the phenomenological quark model compatible with the present-day theory of strong interactions, i.e.

Dark matter admixed strange quark stars in the Starobinsky model [PDF]

open access: yes, 2018
We compute the mass-to-radius profiles for dark matter admixed strange quark stars in the Starobinsky model of modified gravity. For quark matter we assume the MIT bag model, while self-interacting dark matter inside the star is modelled as a Bose ...

Spin and Flavor Strange Quark Content of the Nucleon [PDF]

open access: yesPhys.Rev.D78:014001,2008, 2008
Several spin and flavor dependent parameters characterizing the strangeness content of the nucleon have been calculated in the chiral constituent quark model with configuration mixing (\chiCQM_{config}) which is known to provide a satisfactory explanation of the ``proton spin crisis'' and related issues.

Strange Quark Matter in Stars: A General Overview [PDF]

open access: yesJ.Phys. G31 (2005) S651-S658, 2004
The physics of strange quark matter in the core of compact stars and recent compact star data is reviewed. Emphasis is put on the possible existence of a third family of strange quark stars.

Strange Quark Magnetic Moment of the Nucleon at the Physical Point. [PDF]

open access: yesPhysical Review Letters, 2016
We report a lattice QCD calculation of the strange quark contribution to the nucleon's magnetic moment and charge radius. This analysis presents the first direct determination of strange electromagnetic form factors including at the physical pion mass ...

Electrically charged strange quark stars with a non-linear equation-of-state

open access: yesThe European Physical Journal C, 2019
The properties of electrically charged strange quark stars are investigated. We assume a non-linear equation-of-state, and we obtain numerical solutions to the structure equations.
