The G0 experiment at Jefferson Lab uses elastic, parity-violating electron–proton scattering to study the strange-quark contribution to the proton form factors. A dedicated, special-purpose spectrometer was built for this project. We present results from the recently completed forward-scattering-angle run and compare them with previous experiments ...

Strange quarks in matter [PDF]
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 compact stars [PDF]
Astrophysicists distinguish between three different types of compact stars. These are white dwarfs, neutron stars, and black holes. The former contain matter in one of the densest forms found in the Universe which, together with the unprecedented progress in observational astronomy, make such stars superb astrophysical laboratories for a broad range of

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 ...

Strange-quark content of the proton
Physical Review D, 1988The usual evidence for the strange-quark content of the proton comes from chiral-symmetry breaking as measured in the pion-nucleon sigma term, which involves the proton matrix elements of the scalar-quark densities. Another piece of evidence for it, which involves the proton matrix elements of the pseudoscalar-quark densities, is presented.

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 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 ...

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 ...

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.
