STRANGE MATTER AND STRANGE STARS WITH TSALLIS STATISTICS
International Journal of Modern Physics D, 2007We investigate the properties of β-equilibrated electrically charged neutral strange matter and strange stars at finite temperature in the framework of Tsallis statistics [C. Tsallis, J. Stat. Phys.52 (1988) 479]. As the main result of our study we find out that a QHD description of nuclear matter combined with Tsallis statistics may open new ...

Nuclear Physics A, 1995
Abstract Recent investigations of regions of stability for multi-strange hadronic systems, made up of nucleons and hyperons {p, n, Λ, Ξ0, Ξ−}, are reviewed. Relativistic mean field calculations, designed to reproduce the observed binding energies of ordinary nuclei and of Λ, Ξ and ΛΛ hypernuclei, predict a large class of such objects which are stable

Strange matter at finite temperatures
Nuclear Physics B - Proceedings Supplements, 1989Abstract We present the properties of strange matter at temperatures between 0 and 30 MeV. Finite temperature introduces in most cases only small corrections of quantities describing strange matter, however electron density and Coulomb barrier change significantly. The pressure dependence of the system is also presented.

Combustion of nuclear matter into strange matter
Physical Review D, 1994We study the properties of the combustion of pure neutron matter into strange matter in the framework of relativistic hydrodynamical theory of combustion. Because of the uncertainties in the actual properties of neutron matter, we employ the free neutron, Bethe-Johnson, Lattimer-Ravenhall, and Walecka equations of state and for strange matter we adopt ...

Phase structure of strange matter
Physical Review D, 1993We present a detailed discussion of the phase structure of hadronic matter with finite strangeness content and discuss the thermodynamic conditions for the formation of metastable strange quark droplets ( strangelets'') in relativistic nuclear collisions.

Radioactivity in strange quark matter
Physical Review C, 1987We develop a mass formula for finite lumps of strange quark matter near flavor equilibrium. Our Fermi-gas model includes surface tension and Coulomb energy but not quantum-chromodynamic radiative corrections. Assuming strange matter is stable in bulk, we investigate the radioactive decays of finite strangelets (clumps of strange matter with baryon ...

Properties of strange quark matter
Physical Review D, 1993Assuming that the novel nuclei of [ital A]=370 amu and [ital Z]=14 recently observed in high-energy cosmic rays are really strange quark matter (SQM), the relationship between parameters describing SQM is discussed and the mass formula for SQM is derived by requiring that it yields the observed value of [ital A]=370 amu and [ital Z]=14.

Nuclear Physics A, 2003
Abstract A recent experimental progress of strangeness nuclear physics is reviewed from viewpoint of hyperon-nucleon ( YN ) and hyperon-hyperon ( YY ) interactions. Detailed level structure of Λ hypernuclei has been studied by γ-ray spectroscopy technique using a germanium detector array as well as an NaI counter array, which determined the strengths

Nuclear Physics A, 1987
Abstract We investigate suggestions that quark matter with strangeness per baryon of order unity may be stable. We model this matter at nuclear matter densities as a gas of close packed Λ-particles. From the known mass of the Λ-particle we obtain an estimate of the energy and chemical potential of strange matter at nuclear densities.
