Can we study Quark Matter in the Quenched Approximation

摘要: Abstract We study a quenched SU ( 2 ) lattice gauge theory in which, an attempt to distinguish between timelike and spacelike fields, the ensemble { U μ } is generated from 3-dimensional gauge-Higgs model, link variables being “reconstructed” Higgs fields. The resulting used quark propagation with non-zero chemical potential ; particular, density, chiral superfluid condensates, meson, baryon gauge-fixed propagators are all studied as functions of . While it proves possible alter strength inter-quark interaction by changing parameters dimensionally reduced there no evidence for any region parameter space where quarks exhibit deconfined behaviour or thermodynamic observables scale if was Fermi surface.
