9 v 1 2 A ug 1 99 4 Hadronic screening masses and the magnetic gluon condensate at high temperature
نویسندگان
چکیده
The hadronic screening mass at high temperature (T) in QCD 4 is examined on the basis of the QCD sum rules in (2+1) dimensions. Due to the magnetic gluon con-densate at high T which is expected to be nonvanishing, the screening mass deviates from the asymptotic value 2πT. Also, the screening mass in the vector (pseudo-vector) channel turns out to be heavier than that in the scalar (pseudo-scalar) channel.

We discuss the calculation of electric and magnetic screening masses in SU(2) gauge theory. The temperature dependence of these masses obtained from the long-distance behaviour of spatial correlation functions has been analyzed for temperatures up to 10 4 Tc.

We evaluate the quark-photon vertex non-perturbatively taking into account the gluon condensate at finite temperature. This vertex is related to the previously derived effective quark propagator by a QED like Ward-Takahashi identity. The importance of the effective vertex for the dilepton production rate from a quark-gluon plasma is stressed. PACS numbers: 12.38.Lg Typeset using REVTEX Supporte...
متن کاملEffective mass of phi mesons at finite temperature
The effective mass of phi meson at non-zero temperature is re-examined with an effective chiral Lagrangian. We find that the phi mass decreases with temperature but the effect is small compared to the result obtained from calculations using QCD sum rules. The leading contributions come from kaon loop corrections but vector meson contributions are also important as temperature increases. We disc...

The systematic approach to study bound states in gluodynamics is presented. The method utilizes flow equations together with low-energy phenomenology, that provides the perturbative renormalization scaling in conjuction with the change of the basis to constituent gluon states. The renormalized effective Hamiltonian of gluodynamics up to the second order is obtained at low energies, which provid...

Modifications of hadron masses and some of their basic properties with temperature or nuclear density are considered as one possible signatures for the formation of dense hadronic matter in nuclear collisions. We discuss here some basic results on the temperature dependence of hadron properties obtained from calculations of hadron correlation functions, the chiral condensate as well as the equa...
