Static Electron-Positron Pair Creation in Strong Fields for a Nonlinear Dirac model
We consider the Hartree-Fock approximation of Quantum Electrodynamics, with the exchange term neglected. We prove that the probability of static electron-positron pair creation for the Dirac vacuum polarized by an external field of strength Z behaves as 1 − exp(−κZ2/3) for Z large enough. Our method involves two steps. First we estimate the vacuum expectation of general quasi-free states in ter...
متن کاملKinetics of Vacuum Pair Creation in Strong Electromagnetic Fields
We study vacuum particle antiparticle pair production under action of a strong time dependent space homogeneous electric field at the presence of a constant magnetic field. The kinetic equation for fermions and bosons was derived in the framework of the Schwinger mechanism of vacuum tunnelling. We show the enhancement of pair production for fermions (suppression for bosons) with the increasing ...
متن کاملPair creation by a photon in a strong magnetic field
The process of pair creation by a photon in a strong magnetic field is investigated basing on the polarization operator in the field. The total probability of the process is found in a relatively simple form. The probability exhibits a ”saw-tooth” pattern because of divergences arising when the electron and positron are created at threshold of the Landau energy levels. The pattern will be washe...
متن کاملCharge Renormalization and Static Electron/Positron Pair Production for a Nonlinear Dirac Model with Weak Interactions
The Hartree-Fock approximation of Quantum Electrodynamics provides a rigorous framework for the description of relativistic electrons in external fields. This nonlinear model takes into account the infinitely many virtual electrons of Dirac’s vacuum as well as the Coulomb interactions between all the particles. The state of the system is an infinite-rank projection satisfying a nonlinear equati...
متن کاملCoherent pair creation in linear colliders.
Coherent pair creation during the collision of e + e beams in linear colliders is examined. This includes contributions from both real and virtual photons, where the real photons are predominantly from beamstrahlung. The pair creation probability is shown to be orders of magnitude larger than the corresponding incoherent processes. The energy spectrum is also calculated where the effective thre...
