Space-Time Geometry of Quark and Strange Quark Matter
Chinese Journal of Astronomy and Astrophysics, 2007We study quark and strange quark matter in the context of general relativity. For this purpose, we solve Einstein's field equations for quark and strange quark matter in spherical symmetric space-times. We analyze strange quark matter for the different equations of state (EOS) in the spherical symmetric space-times, thus we are able to obtain the space-

Nuclear Physics B - Proceedings Supplements, 1991
Abstract We discuss the recent developments related to the issue of presence of non-valence strange quark pairs in the proton: their large contribution to the polarized structure functions, σ-term and OZl violation in baryon-meson couplings, and their peaceful coexistence with deep inelastic scattering data and with the successes of non-relativistic ...

Equation of state of strange quark matter and strange star
Physical Review D, 1991Using a relativistic version of the Landau theory of a Fermi liquid and a density-dependent quark-mass approach to confinement, the equation of state of strange quark matter has been derived. This equation of state is used to study the stability and some global properties of a strange quark star.

Strange quark matter and models of strange stars
Astrophysics, 1994In the framework of the MIT bag model we consider absolutely stable strange quark matter consisting of u, d, and s quarks and electrons. For a realistic range of parameters of the quark bag we compute the threshold density for the appearance of strange quark matter that is realized on the surface of self-sustaining strange stars. On the basis of twelve

Neutrino emissivity of strange quark matter
Physical Review D, 1990We study the neutrino emissivity of three-flavor degenerate "strange matter" by using a thermodynamic potential calculated to second order in ${\ensuremath{\alpha}}_{c}$ and by solving the Gell-Mann-Low equation for the screened charge ${\ensuremath{\alpha}}_{c}$. No reduction in the emissivity at higher densities is found.

AIP Conference Proceedings, 1992
We survey the field of strange particle nuclear physics, starting with the spectroscopy of strangeness S=−1 Λ hypernuclei, proceeding to an interpretation of recent data on S=−2 ΛΛ hypernuclear production and decay, and finishing with some speculations on the production of multi‐strange nuclear composites (hypernuclei or ‘‘strangelets’’) in ...

Journal of Physics G: Nuclear and Particle Physics, 2002
This conference opening talk presents a short review of recent progress in strangeness production systematics, notably the topic of energy dependence, up to RHIC. The data are confronted with the statistical hadronization model which helps to answer the question of their connection to the parton–hadron phase transformation occuring at upper SPS ...

Strange Quark Matter and Strange Quark Stars
2017New forms of matter such as super-hypernuclei(strange quark matter) and superhypernuclear stars(strange quark stars) are discussed in some detail, based on the so-called “Bodmer–Terazawa–Witten hypothesis” assuming that they are stable or quasi-stable.

Strangeness in paradise: The strange quark as a probe of QCD
Acta Physica Hungarica A) Heavy Ion Physics, 1996I review the arguments for considering the strange quark as a probe of changes in the QCD vacuum, and of the formation of a quark-gluon plasma, in particular. I survey existing data showing enhanced production of strange hadrons in relativistic heavy ion collisions and analyse their implications in the context of thermal and microscopic reaction models.
