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 ...

RIGIDLY ROTATING STRANGE QUARK STARS

International Journal of Modern Physics D, 2005
In this article, we study rotating strange quark stars in the context of general relativity. For this purpose we consider perfect fluid model composed of strange quark matter with electromagnetic field in the Gödel Universe which has rigid rotation. We solve Einstein's field equations by using equation of state for strange quark matter.

Cylindrically Symmetric Diffusion Model for Relativistic Heavy‐Ion Collisions

Annalen der Physik, Volume 536, Issue 5, May 2024.
To account for particle production in relativistic heavy‐ion collisions at the Large Hadron Collider, a relativistic diffusion model with cylindrical symmetry is derived from nonequilibrium–statistical considerations. It propagates an initial state based on quantum chromodynamics in time toward a thermal equilibrium limit.

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.

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.

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.

Quark-Antiquark Condensates in the Hadronic Phase

, 2005
We use a hadron resonance gas model to calculate the quark-antiquark condensates for light (up and down) and strange quark flavors at finite temperatures and chemical potentials.

Strangeness and Quark--Gluon Plasma [PDF]

arXiv: Nuclear Theory, 2011
I review the foundational motivation which led us to the ultra relativistic heavy ion collision research at SPS, RHIC and now LHC: the quantum vacuum structure; the deconfined nature of quark-gluon plasma (QGP) phase filling the Universe for the first 30$ $s after the big-bang; the origin of stable matter mass; and of the origin of flavor.

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.
