Strange Quark Matter in a Strong Magnetic Field

East European Journal of Physics, 2013
Thermodynamic properties of strange quark matter are considered in strong magnetic fields up to 1020 G. It is shown that the appearance of the longitudinal (along the magnetic field) instability beyond some critical magnetic field precludes the formation

Modified F(R,T)-Gravity Model Coupled with Magnetized Strange Quark Matter Fluid

Mathematics
This research note presents the properties of the F(R,T)-gravity model in combination with magnetized strange quark matter. We obtain the equation of state for the magnetized strange quark matter in the F(R,T)-gravity model endowed with the Lagrangian ...

QCD in neutron stars and strange stars

, 2011
This paper provides an overview of the possible role of Quantum Chromo Dynamics (QDC) for neutron stars and strange stars. The fundamental degrees of freedom of QCD are quarks, which may exist as unconfined (color superconducting) particles in the cores ...

Stellar model with non-zero strange quark mass ( $$m_s\ne 0$$ m s ≠ 0 ) and Mak–Harko density profile admitting observational results

European Physical Journal C: Particles and Fields
This article describes the configuration of strange quark stars composed of three flavour quarks in hydrostatic equilibrium considering the energy density profile of Mak and Harko and non-zero strange quark mass ( $$m_s\ne {0}$$ m s ≠ 0 ).

Probing QCD critical fluctuations from the yield ratio of strange hadrons in relativistic heavy-ion collisions

Physics Letters B, 2020
By analyzing the available data on strange hadrons in central Pb+Pb collisions from the NA49 Collaboration at the Super Proton Synchrotron (SPS) and in central Au+Au collisions from the STAR Collaboration at the Relativistic Heavy-Ion Collider (RHIC) in ...

Strange and charm quark-pair production in strong non-Abelian field

, 2009
We have investigated strange and charm quark-pair production in the early stage of heavy ion collisions. Our kinetic model is based on a Wigner function method for fermion-pair production in strong non-Abelian fields.

String breaking by light and strange quarks in QCD

Physics Letters B, 2019
The energy spectrum of a system containing a static quark anti-quark pair is computed for a wide range of source separations using lattice QCD with Nf=2+1 dynamical flavours.

Determining the strange and antistrange quark distributions of the nucleon

, 2011
The difference between the strange and antistrange quark distributions, $\delta s(x)=s(x)-\sbar(x)$, and the combination of light quark sea and strange quark sea, $\Delta (x)=\dbar(x)+\ubar(x)-s(x)-\sbar(x)$, are originated from non-perturbative ...

Charmed states and flavour symmetry breaking

EPJ Web of Conferences, 2018
Extending the SU(3) flavour symmetry breaking expansion from up, down and strange sea quark masses to partially quenched valence quark masses allows an extrapolation to the charm quark mass.

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

, 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.
