چکیده
We examine the parity violating terms generated by the box diagram in QED3 at finite temperature. These lead to both extensive as well as non-extensive effective actions, which have very distinct behavior in the long wavelength and static limits. We discuss a large gauge Ward identity for the leading terms in the static limit, whose solution coincides with the effective action proposed earlier.

Parity-violating electromagnetic interactions in QED3 at finite temperature
We study the parity-breaking terms generated by the box diagram in 2+1 dimensional thermal QED. These lead, in the long wave limit, to a gauge invariant extensive action which behaves as 1/T at high temperature. In contrast, the effective action in the static limit involves leading non-extensive terms proportional to 1/T 3 at high temperature, which violate large gauge invariance. We derive a n...
متن کاملInduced Lorentz and PCT Symmetry Breaking in an External Electromagnetic Field
In this work we derive the Lorentz-PCT-violating effective action for a fermion in a constant and uniform electromagnetic field using the Fock-Schwinger proper time method and extract the exact value of the coefficient of the nonperturbatively induced Chern-Simons term. Lattely, there has been increasing interest in extensions of quantum electrodynamics (QED) and the Standard Model (SM), where ...
متن کاملParity symmetry restoration in QED 3 at high temperature and finite density
We investigate the properties of quantum electrodynamics (QED3) in two spatial dimensions at finite temperature and density. The static as well as the dynamical properties of the planar plasma are calculated using the real time formalism of quantum field theory. It is shown, that due to the presence of the parity breaking Chern-Simons term, the propagating modes of the photon consists of two lo...

Vacuum effects in (2+1)-dimensional quantum electrodynamics (QED) with the topological Chern-Simons term are considered. The photon polarization operator is studied and the decay rate for the electron-positron photoproduction γ → e+ e− is presented as a function of the photon energy and external field strength. The radiatively induced electron mass shift in an external magnetic field is investi...
متن کاملElectromagnetic radiative corrections in parity-violating electron-proton scattering
QED radiative corrections have been calculated for leptonic and hadronic variables in parityviolating elastic ep scattering. For the first time, the calculation of the asymmetry in the elastic radiative tail is performed without the peaking-approximation assumption in hadronic variables configuration. A comparison with the PV-A4 data validates our approach. This method has been also used to eva...
