Title: Strange tribaryons

Abstract

We use two-body potentials derived from a constituent quark cluster model to analyze the bound-state problem of the {sigma}NN system. The observables of the two-body subsystems, NN and {sigma}N, are well reproduced. We do not find {sigma}NN bound states, but there are two attractive channels with a resonance close above the three-body threshold. These channels are the (I,J)=(1,1/2) and (0,1/2), their quantum numbers, widths and energy ordering consistent with the recently reported strange tribaryons from the {sup 4}He(K{sub stopped}{sup -},N) reactions in the KEK PS E471 experiment.

  • We determine all possible equilibrium sequences of compact strange-matter stars with nuclear crusts, which range from massive strange stars to strange white dwarf{endash}like objects (strange dwarfs). The properties of such stars are compared with those of their nonstrange counterparts{emdash}neutron stars and ordinary white dwarfs. The main emphasis of this paper is on strange dwarfs, which we divide into two distinct categories. The first one consists of a core of strange matter enveloped within ordinary white dwarf matter. Such stars are hydrostatically stable with or without the strange core and are therefore referred to as {open_quote}{open_quote}trivial{close_quote}{close_quote} strange dwarfs. This is differentmore » for the second category which forms an entirely new class of dwarf stars that contain nuclear material up to 4{times}10{sup 4} times denser than in ordinary white dwarfs of average mass, {ital M}{approximately}0.6 {ital M}{sub {circle_dot}}, and still about 400 times denser than in the densest white dwarfs. The entire family of such dwarfs, denoted {ital dense strange dwarfs}, owes its hydrostatic stability to the strange core. A striking features of strange dwarfs is that the entire sequence from the maximum-mass strange star to the maximum-mass strange dwarf is stable to radial oscillations. The minimum-mass star is only conditionally stable, and the sequences on both sides are stable. Such a stable, continuous connection does not exist between ordinary white dwarfs and neutron stars, which are known to be separated by a broad range of unstable stars. We find an expansive range of very low mass (planetary-like) strange-matter stars (masses even below 10{sup {minus}4} {ital M}{sub {circle_dot}} are possible) that arise as natural dark-matter candidates, which if abundant enough in our Galaxy, should be seen in the gravitational microlensing searches that are presently being performed. {copyright} {ital 1995 The American Astronomical Society.}« less
  • In this paper we discuss preliminary measurements of antiproton production in 11.5 A GeV/c Au+Pb nucleus collisions in Experiment 864 at the Brookhaven AGS. By comparing the E864 measurements with those of Experiment 878, we can infer the production of antihyperons in these collisions via the {open_quotes}feed-down{close_quotes} contribution of antiprotons from the decay of the antihyperon. This comparison indicates that the production of strange antibaryons is greatly enhanced, and presents significant challenges for thermal and transport models of heavy-ion collisions. {copyright} {ital 1997 American Institute of Physics.}
  • We present results on strange and multistrange particle production in Au + Au collisions at {radical}s{sub NN} = 62.4 GeV as measured with the STAR detector at RHIC. Midrapidity transverse momentum spectra and integrated yields of K{sub S}{sup 0}, {lambda}, {Xi}, and {Omega} and their antiparticles are presented for different centrality classes. The particle yields and ratios follow a smooth energy dependence. Chemical freeze-out parameters, temperature, baryon chemical potential, and strangeness saturation factor obtained from the particle yields are presented. Intermediate transverse momentum (p{sub T}) phenomena are discussed based on the ratio of the measured baryon-to-meson spectra and nuclear modificationmore » factor. The centrality dependence of various measurements presented show a similar behavior as seen in Au + Au collisions at {radical}s{sub NN} = 200 GeV.« less
  • Using 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.
