Damping Rate of a Scalar Particle in Hot Scalar Qed
In contrast to the damping of partons in a quark-gluon plasma, the damping of a scalar particle in a hot scalar QED plasma can be calculated to leading order for the whole momentum range using the Braaten-Pisarski method. In this way the evolution of the logarithmic infrared singularity caused by the exchange of a transverse photon from soft to hard momenta can be studied. The damping rates of ...
متن کاملReal-time Relaxation of Condensates and Kinetics in Hot Scalar Qed: Landau Damping
The real time evolution of field condensates with soft length scales ∼ k−1 > (eT )−1 is solved in hot scalar electrodynamics. We rederive the HTL effective action using the techniques of non-equilibrium field theory for small amplitude condensates. We find that transverse gauge invariant condensates relax as 1/t2 and longitudinal condensates associated with plasmon (charge density) excitations ...
متن کاملReal-time Relaxation and Kinetics in Hot Scalar Qed: Landau Damping
The real time evolution of non-equilibrium expectation values with soft length scales ∼ k−1 > (eT )−1 is solved in hot scalar electrodynamics, with a view towards understanding relaxational phenomena in the QGP and the electroweak plasma. We find that the gauge invariant non-equilibrium expectation values relax via power laws to asymptotic amplitudes that are determined by the quasiparticle pol...
متن کاملMonopole percolation in scalar QED
One of the most challenging unsolved questions that arise in the application of lattice theory to particle physics is to understand the nature of the phase structure of lattice Quantum Electrodynamics. Numerical simulations of pure gauge Lattice QED with periodic boundary conditions and using the compact gauge action S = β cos θ show the existence of a first order phase transition [1]. This avo...
متن کاملFermion Damping in a Fermion - Scalar Plasma
In this article we study the dynamics of fermions in a fermion-scalar plasma. We begin by obtaining the effective in-medium Dirac equation in real time which is fully renormalized and causal and leads to the initial value problem. For a heavy scalar we find the novel result that the decay of the scalar into fermion pairs in the medium leads to damping of the fermionic excitations and their in-m...
