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 ...

Neutron stars and strange stars in the chiral SU(3) quark mean field model [PDF]

, 2005
We investigate the equations of state for pure neutron matter and strange hadronic matter in $\beta$-equilibrium, including $\Lambda$, $\Sigma$ and $\Xi$ hyperons. The masses and radii of pure neutron stars and strange hadronic stars are obtained.

Properties of strange-matter stars [PDF]

AIP Conference Proceedings, 1995
This paper deals with an investigation of the properties of hypothetical strange‐matter stars, which are composed of u, d, s, quark matter whose energy per baryon number lies below the one of 56Fe (Witten’s strange matter hypothesis). Observable quantities which allow to distinguish such objects from their ‘‘conventional’’ counterparts, neutron stars ...

Strange matter

International Journal of Modern Physics A
Pulsar-like objects are extremely compact, with an average density that exceeds nuclear saturation density, where the fundamental strong interaction plays an essential role, particularly in the low-energy regime. The internal structures and properties of those objects are profoundly connected to phenomena such as supernova explosions, gamma-ray bursts (

Strange Exotic States and Compact Stars [PDF]

, 2006
We discuss the possible appearance of strange exotic multi-quark states in the interior of neutron stars and signals for the existence of strange quark matter in the core of compact stars.

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.

Thermal Evolution and Light Curves of Young Bare Strange Stars [PDF]

, 2002
The cooling of a young bare strange star is studied numerically by solving the equations of energy conservation and heat transport for both normal and superconducting strange quark matter inside the star.

Strangeness and charm in nuclear matter [PDF]

Nuclear Physics A, 2013
The properties of strange ($K$, $\bar K$ and $\bar K^*$) and open-charm ($D$, $\bar D$ and $D^*$) mesons in dense matter are studied using a unitary approach in coupled channels for meson-baryon scattering. In the strangeness sector, the interaction with nucleons always comes through vector-meson exchange, which is evaluated by chiral and hidden gauge ...

Seeding of Strange Matter with New Physics [PDF]

, 1997
At greater than nuclear densities, matter may convert into a mixture of nucleons, hyperons, dibaryons, and strangelets, thus facilitating the formation of strange matter even before the onset of the quark-matter phase transition.
