Vacuum polarization and the electric charge of the positron


Journal Article

We show that higher-order vacuum polarization would contribute a measurable net charge to atoms, if the charges of electrons and positrons do not balance precisely. We obtain the limit Qe+Qē<10-18e for the sum of the charges of electron and positron. This also constitutes a new bound on certain violations of PCT invariance. © 1992 The American Physical Society.
