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.

The Phase Diagram of High Temperature QCD with Three Flavors of Improved Staggered Quarks

, 2003
We report on progress in our study of high temperature QCD with three flavors of improved staggered quarks. Simulations are being carried out with three degenerate quarks with masses less than or equal to the strange quark mass, $m_s$, and with ...

A Gaussian Model for Anisotropic Strange Quark Stars [PDF]

, 2015
For studying the anisotropic strange quark stars, we assume that the radial pressure inside an anisotropic star can be obtained simply by isotropic pressure plus an additional Gaussian term with three free parameters (A, μ and χ).

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.

Perturbative and nonperturbative contributions to the strange quark asymmetry in the nucleon

, 2012
There are two mechanisms for the generation of an asymmetry between the strange and anti-strange quark distributions in the nucleon: nonperturbative contributions originating from nucleons fluctuating into virtual baryon-meson pairs such as $\Lambda K ...

Stable strange quark matter objects with running masses and coupling constant

Nuclear Physics B, 2017
We improve our recently proposed unified description for strange quark matter (SQM) objects, in the way that analytical expressions are derived and used to calculate the distribution of particles inside an SQM object.

Hawking-Unruh Hadronization and Strangeness Production in High Energy Collisions

Advances in High Energy Physics, 2014
The thermal multihadron production observed in different high energy collisions poses many basic problems: why do even elementary, e+e- and hadron-hadron, collisions show thermal behaviour?

Nucleon strangeness polarization from $$\varLambda /\bar{\varLambda }$$ Λ/Λ¯ hyperon production in polarized proton–proton collision at RHIC

European Physical Journal C: Particles and Fields, 2019
We calculate the inclusive production of a polarized $$\varLambda $$ Λ or $$\bar{\varLambda }$$ Λ¯ hyperon from the single longitudinally polarized proton and proton (pp) collision at RHIC.

Five-Dimensional Strange Quark Bianchi Type-I Cosmological Model in The Framework of Saez Ballester Theory of Gravity

East European Journal of Physics
In this paper, we have constructed a five-dimensional Bianchi type I cosmological model with strange quark matter in the context of Saez-Ballester theory of gravity.
