Abstract


Jet quenching signal associated with the hard process QGP study of methods have been studied more thoroughly, we can be applied to the study QED medium to study the nature of the medium of QED. Jet quenching in the QGP is an important aspect of the research is the theoretical framework of the QCD use done some simplified GW model, calculate the energetic parton jet across the QGP target parton gluon multiple scattering induced radiation caused loss of energy as well as energy, consider the case of the heat medium absorption gluon study the QED media is in the the QED theoretical framework, we can get rid of the the QCD framework GW model color interaction transform for QED framework GW model, we calculate the energy of high-energy electron spray Note across the electron - positron plasma when the target particles multiple scattering induced radiation photon energy loss, and consider the photon absorption in the case of the heat medium. The GW model GLV calculation results show that jets of energetic parton energy loss can use opacity to expand given the lower initial energy injection, multiple scattering induced gluon radiation, the less energy loss, for the same energy injection, high-level the opacity of energy loss than low-level the opacity of energy loss less so in the high-energy under extreme conditions can be ignored, GLV opacity expand technical calculation results show that part of the multiple scattering induced gluon radiation The energy loss and the scattering process of the sub-injection through the thickness L of the target was squared dependency. Energetic parton jet in the hot medium the Note and medium target parton interactions may be absorbed from the heat medium gluon detailed balance effect, the calculated results show that taking into account the detailed balance effect for part of the medium-energy sub-injectors have an important impact must be considered in the calculation of the energy loss injection, high energy parton detailed balance effect is not obvious, the contribution of heat absorption is negligible, the detailed balance effect can not consider. By conversion GW model calculation energetic electrons sprayed Note crossing electron - positron plasma, when the target particle multiple scattering induced radiation photon energy loss occurs and considering the absorbed photon energy is obtained in the case of a heat medium and calculation results show that, in the static the QED medium electron injection occurs for the electronic spray injection and media in the target particle elastic collisions result in the energy loss, due to loss of radiation energy of the photon and the energy is obtained due to the absorption of photons proportional to the thickness of the with QED medium target L When the injection energy and the ratio of the medium temperature take LT; 100, elastic collision the major portion of the total amount of energy loss. In the QED medium taking into account the evolution of the electronic injection due to the loss of radiation energy of the photon, and due to the absorption of photon energy obtained QED medium thickness is no longer directly proportional relationship, and the curve will become more smooth. Detailed balance effect of the process, when the temperature T of the medium and the injection energy E has the same order of magnitude, the effect is obvious, must consider the detailed balance effect, if T is much smaller than the E, the detailed balance effect is not obvious can be ignored.
