Quark mass density - and temperature - dependent model for bulk strange quark matter
It is shown that the quark mass density-dependent model can not be used to explain the process of the quark deconfinement phase transition because the quark confinement is permanent in this model. A quark mass densityand temperature-dependent model in which the quark confinement is impermanent has been suggested. We argue that the vacuum energy density B is a function of temperature and satisfi...
متن کاملBulk viscosity of strange quark matter in density-dependent quark mass model and dissipation of r-modes in strange stars
We study the bulk viscosity of strange quark matter(SQM) in density dependent quark mass model(DDQM) under the background of selfconsistent thermodynamics. The correct formulae, with which the viscosity can be evaluated, are derived. We also find that the viscosity in DDQM can be higher by 2 to 3 orders of magnitude than MIT bag model. We calculate the damping time scales due to viscosity coupl...
متن کاملStudy of Proto Strange Stars (pss) in Temperature and Density Dependent Quark Mass Model
We report on the study of the mass-radius (M-R) relation and the radial oscillations of proto strange stars. For the quark matter we have employed the well known density dependent quark mass model and its very recent modification, the temperature and density dependent quark mass model. We find that the maximum mass the star can support increases significantly with the temperature of the star in...

متن کاملThe NJL model and strange quark matter
The stability of strange quark matter is studied within the Nambu JonaLasinio model with three different parameter sets. The model Lagrangian contains 4-fermion (with and without vector interaction) and 6-fermion terms; the minimum energy per baryon number as a function of the strangeness fraction of the system is compared to the masses of hyperons having the same strangeness fraction, and cohe...
