N ov 1 99 5 A search for stable strange quark matter nuggets in helium
A search for stable strange quark nuggets has been conducted in helium and argon using a high sensitivity mass spectrometer. The search was guided by a mass formula for strange quark nuggets which suggested that stable strange helium might exist at a mass around 65 u. The chemical similarity of such “strangelets” to noble gas atoms and the gravitational unboundedness of normal helium result in ...
متن کاملStrange Goings on in Quark Matter
The study of hadronic matter at high baryon density has recently attracted a lot of interest. At zero baryon density chiral symmetry is broken by a quark-anti-quark condensate. At high density condensation in the quarkanti-quark channel is suppressed. Instead, attractive interactions in the color anti-symmetric quark-quark channel favor the formation of diquark condensates. As a consequence, co...
متن کاملMagnetized Quark and Strange Quark Matter in the Spherical Symmetric Space-Time Admitting Conformal Motion
In this paper, we have examined magnetized quark and strange quark matter in the spherical symmetric space-time admitting one-parameter group of conformal motions. For this purpose, we have solved Einstein’s field equations for spherical symmetric space-time via conformal motions. Also, we have discussed the features of the obtained solutions.
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 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-...
