Vacuum polarization and the electric charge of the positron.

چکیده
We show that higher-order vacuum polarization would contribute a measureable net charge to atoms, if the charges of electrons and positrons do not balance precisely. We obtain the limit |Q e + Q ¯ e | < 10 −18 e for the sum of the charges of electron and positron. This also constitutes a new bound on certain violations of PCT invariance.

Analysis of Electric Field and Polarization of SF6 Circuit Breaker to Approach a Suitable Structure
Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...
متن کاملWeak-Equivalence Principle Violation and Mass Change of Charged Matter due to Vacuum Polarization
Vacuum polarization by electric fields is a well established fact. Assuming that anti-matter has negative gravitational properties, the fluctating electric dipoles from the quantum vacuum may also have gravitational dipolar properties. A model is developed that describes how electric fields could gravitationally polarize the vacuum causing gravitational screening or anti-screening effects. This...
متن کاملClassical electrodynamics with vacuum polarization: electron self-energy and radiation reaction
The region very close to an electron (r ∼ r0 = e /mc ≈ 2.8 × 10−13 cm) is, according to quantum electrodynamics, a seething maelstrom of virtual electron-positron pairs flashing in and out of existence. To take account of this well-established physical reality, a phenomenological representation for vacuum polarization is introduced into the framework of classical electrodynamics. Such a model e...

In this report, the distribution and deviation of electric field in the active medium of the TE CO2 laser has been investigated due to the injection of net electron charge beam as a plasma generator. Some parameters of system have been considered, such as density and mean-free-path of injected charge beam. The electric potential and electric field distribution have been simulated by solving the...
