Ultrarelativistic Electron-Positron Plasma
Markus H. Thoma
Ultrarelativistic electron-positron plasmas can be produced in high-intensity laser fields and play a role in various astrophysical situations. Their properties can be calculated u…
Dielectric Functions and Dispersion Relations of Ultra-Relativistic Plasmas with Collisions
M. E. Carrington, T. Fugleberg, D. Pickering +1
In the present paper we calculate the dielectric functions of an ultra-relativistic plasma, such as an electron-positron or a quark-gluon plasma. We use classical transport theory…
Gluon Condensate and Non-Perturbative Quark-Photon Vertex
M. G. Mustafa, A. Schaefer, M. H. Thoma
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 qu…
Quark Dispersion Relation and Dilepton Production in the Quark-Gluon Plasma
Andre Peshier, Markus H. Thoma
Under very general assumptions we show that the quark dispersion relation in the quark-gluon plasma is given by two collective branches, of which one has a minimum at a non-vanishi…
Gluon condensate, quark propagation, and dilepton production in the quark-gluon plasma
M. G. Mustafa, A. Sch"afer, M. H. Thoma
A calculation of the thermal quark propagator is presented taking the gluon condensate above the critical temperature into account. The quark dispersion relation and the dilepton p…
One-loop self energies at finite temperature
A. Peshier, K. Schertler, M. H. Thoma
The complete one-loop self energies (real and imaginary parts) for photons, gluons, electrons and quarks at finite temperature are calculated numerically and compared to the result…
Strange quark matter with effective quark masses
K. Schertler, C. Greiner, M. H. Thoma
The properties of strange quark matter at zero temperature are investigated including medium effects. The quarks are considered as quasiparticles which acquire an effective mass ge…
Production of energetic dileptons with small invariant masses from the quark-gluon plasma
M. H. Thoma, C. T. Traxler
The resummation technique of Braaten and Pisarski is used for a complete calculation of the -contribution to the production rate of dileptons with energy E >> T and invari…
Medium effects in strange quark matter and strange stars
K. Schertler, C. Greiner, M. H. Thoma
We investigate the properties of strange quark matter at zero temperature including medium effects. The quarks are considered as quasiparticles which acquire an effective mass gene…
Damping Rate and Lyapunov Exponent of a Higgs Field at High Temperature
T. S. Biro, M. H. Thoma
The damping rate of a Higgs field at zero momentum is calculated using the Braaten-Pisarski method and compared to the Lyapunov exponent of the classical SU(2) Yang-Mills Higgs sys…
A Dynamical Model of Color Confinement
S. Loh, T. S. Biro, U. Mosel +1
A dynamical model of confinement based on a transport theoretical description of the Friedberg-Lee model is extended to explicit color degrees of freedom. The string tension is rep…
Photon Emission from a Parton Gas at Chemical Non-Equilibrium
Christoph T. Traxler, Markus H. Thoma
We compute the hard photon production rate of a chemically non-equilibrated quark-gluon plasma. We assume that the plasma is already thermally equilibrated, i.~e. describable by a…
Hard photon production rate of a quark-gluon plasma at finite quark chemical potential
C. T. Traxler, H. Vija, M. H. Thoma
We compute the photon production rate of a quark-gluon plasma (QGP) at finite quark chemical potential using the Braaten-Pisarski method, thus continuing the work of Kapusta, L…
Parton Interaction Rates in the Quark-Gluon Plasma
Markus H. Thoma
The transport interaction rates of elastic scattering processes of thermal partons in the quark-gluon plasma are calculated beyond the leading logarithm approximation using the eff…
