The lack of vacuum polarization in quantum electrodynamics with spinors in fermion equations

TL;DR

This paper explores modified versions of quantum electrodynamics with spinors where vacuum polarization is absent, leading to new physical implications that could be experimentally tested.

Contribution

It introduces variants of QED that eliminate the need for vacuum polarization, offering a novel perspective on fermion vacuum structure.

Findings

Vacuum polarization is unnecessary in the new QED variants.

New physical consequences arise from the modified fermion vacuum.

Potential for future experimental verification.

Abstract

In this paper, the versions of quantum electrodynamics (QED) with spinors in fermion equations are briefly examined. In the new variants of the theory, the concept of vacuum polarization is unnecessary. The new content of fermion vacuum (without the Dirac sea) in the examined versions of QED leads to new physical consequences, part of which can be tested experimentally in the future.
