Equation of state of cold and dense QCD matter in resummed perturbation theory
نویسندگان
چکیده
We discuss the hard dense loop resummation at finite quark mass and evaluate equation of state (EoS) cold QCD matter in $\ensuremath{\beta}$ equilibrium. The sector has an effect lowering baryon number density EoS turns out to have much smaller uncertainty than perturbative estimate. Our numerical results favor smooth matching between from resummed calculation high extrapolated nuclear region. also point that speed sound our slightly exceeds conformal limit.

A systematic loop expansion is formulated in terms of full propagators and vertices. It is based on an expansion of the general solution of an exact non-perturbative flow equation.

The QCD equation of state is not often discussed in cosmology. However, the relic density of weakly interacting massive particles (WIMPs) depends on the entropy and the expansion rate of the Universe when they freeze out, at a temperature in the range 400 MeV – 40GeV, where QCD corrections are still important. We use recent analytic and lattice calculations of the QCD pressure to produce a new ...

Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable equation of state for the cold quark matter, are expanded using the reductive perturbation method. It is shown that in small amplitude approximation, such a medium should be co...
