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

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.

Strangeness Nuclear Physics And Strange Matter In Universe
AIP Conference Proceedings, 2010We introduce physics interests of hypernuclei related to astrophysics. Particularly, some remarkable information from precision spectroscopic studies of hypernuclei has been provided, which should be taken into consideration on arguments on hyperon constituent in a neutron star core.

The concept of waves associated with any material particle has been a considerable boost to theoretical physics, and it appears to be in accordance with many experimental results. Some relativistic properties of these assumed waves are studied in comparison to other physical waves.

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

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.

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 ...

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
