Properties of strange quark matter

Physical Review D, 1993
Assuming 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.

Strange quarks in the deuteron

Physical Review D, 1990
We consider elastic electroweak lepton-deuteron scattering as a means to extract information on both vector and axial-vector isoscalar currents, and thus the strange- (and heavier-) quark content of the deuteron. Parity violation in electron-deuteron scattering is examined in some detail. Numerical estimates are made, using a simple model when required,

Radioactivity in strange quark matter

Physical Review C, 1987
We 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, 1988
The 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.

Strange quarks in the nucleon

Journal of Physics G: Nuclear and Particle Physics, 2006
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 ...
