The Study Of Dielectric Properties Of Strongly Interacting Matter

There are two frameworks: the finite temperature theory and the kinetic theory for studying strongly interacting matter. The kinetic theory is a statistical theory that can describe the non-equilibrium phenomena in basic, the kinetic equation for the nuclear matter system have been formed under the general frame of the statistical theory and its dynamic basic is the quantum hadrodynamics (QHD), which is the component particles of the system obey; the kinetic equations for the QGP have been formed under the general frame of the statistical theory and its dynamic basic is the quantum chromodynam-ics(QCD), which the component particle of the system obey. Unfortunately, it's difficult to obtain the non-equilibrium functions by strictly solving the QGP kinetic equations. At present, semi-classical kinetic theory is more successful than other theories.Here, based on the kinetic theory, we have mainly discussed the dielectric properties effects for strongly interacting matter. Our discussion can be divided into two aspects. Firstly, based on the QHD-1 field equation, the dielectric constant of nuclear matter with the wNN interaction has been obtained in the framework of kinetic theory. Furthermore, the character and physical background of the dielectric constant at high temperature is analyzed in detail. Secondly, from QGP classical equation, adopting the iterating method, we calculate the dielectric constant beyond HTL approximation. Then we compare dielectric constant on the level of beyond HTL with that on the level of HTL.
