Title: Phase transition from hadronic matter to quark matter

Abstract

We study the phase transition from two-flavor nuclear matter to quark matter. A mean field model, constructed at the quark level, is used to give the equation of state for nuclear matter, while the equation of state for color superconducting quark matter is calculated within the NJL model. It is found that at low temperature, the phase transition from nuclear to color superconducting quark matter will take place when the density is of order 2.5{rho}{sub 0}-5{rho}{sub 0}. At zero density, the quark phase will appear when the temperature is larger than about 148 MeV. Within the mean field treatment, the phase transition from nuclear matter to quark matter is always first order, whereas the transition between color superconducting quark matter and normal quark matter is second order.

  • We study the phase transition from nuclear matter to quark matter within the SU(3) quark mean field model and NJL model. The SU(3) quark mean field model is used to give the equation of state for nuclear matter, while the equation of state for color superconducting quark matter is calculated within the NJL model. It is found that at low temperature, the phase transition from nuclear to color superconducting quark matter will take place when the density is of order 2.5?0 - 5?0. At zero density, the quark phase will appear when the temperature is larger than about 148 MeV.more » The phase transition from nuclear matter to quark matter is always first order, whereas the transition between color superconducting quark matter and normal quark matter is second order.« less
  • The density of the number of states of colorless quark-gluon bags is determined. This result is used to calculate the partition function of a gas of bags with van der Waals exclusion of their proper volumes. It is shown that the requirement that the bags be colorless has a decisive influence on the thermodynamic properties of this system and leads to a first-order phase transition between hadronic and quark-gluon matter.
  • A convolution form of the free energy density of the thermodynamic system of hadrons is given on the basis of the convolution formula which yields a general form of the statistical bootstrap equation. It is shown that in the thermodynamic limit this free energy density has a typical singular form, which presents a phase transition between hadronic and quark matter, in the same way as magnetic transitions and classical liquid-gas transitions. The characteristic multiplicity distribution is predicted as a signal of the disordered state.
  • We present a mechanism for the separation of strangeness from antistrangeness in the deconfinement transition. For a net strangeness of zero in the total system, the population of s quarks is greatly enriched in the quark-gluon plasma, while the s-bar quarks drift into the hadronic phase. This separation could result in ''strangelet'' formation, i.e., metastable blobs of strange-quark matter, which could serve as a unique signature for quark-gluon plasma formation in heavy-ion collisions.
  • We investigate the possibility and consequences of phase transitions from an equation of state (EOS) describing nucleons and hyperons interacting via mean fields of {sigma}, {omega}, and {rho} mesons in the recently improved quark-meson coupling (QMC) model to an EOS describing a Fermi gas of quarks in an MIT bag. The transition to a mixed phase of baryons and deconfined quarks, and subsequently to a pure deconfined quark phase, is described using the method of Glendenning. The overall EOS for the three phases is calculated for various scenarios and used to calculate stellar solutions using the Tolman-Oppenheimer-Volkoff equations. The resultsmore » are compared with recent experimental data, and the validity of each case is discussed with consequences for determining the species content of the interior of neutron stars.« less
