Strangelets and Strange Quark Matter
As it has been discussed widely during this conference, strangeness opens a new dimensions to nuclear physics. Insofar, systems with strangeness number S = −1,−2 have been discussed. Here we want to examine the unknown domain of finite nuclear systems with S < −2. There have been speculations about the existence of finite systems of strange quark matter (strangelets) and strange hadronic matter...
متن کاملRatio of strange to non - strange quark condensates in
Laplace transform QCD sum rules for two-point functions related to the strangenesschanging scalar and pseudoscalar Green’s functions ψ(Q2) and ψ5(Q 2), are used to determine the subtraction constants ψ(0) and ψ5(0), which fix the ratio Rsu ≡ <ūu> . Our results are ψ(0) = −(1.06±0.21)×10−3 GeV, ψ5(0) = (3.35±0.25)×10 −3 GeV, and Rsu ≡ <ūu> = 0.5 ± 0.1. This implies corrections to kaon-...
متن کاملStrange quark matter attached to string cloud in general scalar tensor theory of gravitation
Bianchi type-VI0 space time with strange quark matter attached to string cloud in Nordtvedt [1] general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger [2] is obtained. The field equations have been solved by using the anisotropy feature of the universe in the Bianchi type-VI0 space time. Some important features of the model, thus obtained, have been di...
متن کاملStrange quark matter with dynamically generated quark masses
Bulk properties of strange quark matter (SQM) are investigated within the SU(3) Nambu–Jona-Lasinio model. In the chiral limit the model behaves very similarly to the MIT bag model which is often used to describe SQM. However, when we introduce realistic current quark masses, the strange quark becomes strongly disfa-vored, because of its large dynamical mass. We conclude that SQM is not absolute...
متن کاملStrange Quark Matter and Compact Stars
Astrophysicists distinguish between three different kinds 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, makes such stars superb astrophysical laboratories for a broad range of most striking physical phenomena. These r...
