ADDENDUM to the papers on the Weinberg Theory

TL;DR

This paper discusses how the Weinberg-Tucker-Hammer equations generalize the standard $j=1$ massless equations, highlighting their significance as a special case and exploring potential implications.

Contribution

It demonstrates that the Weinberg-Tucker-Hammer equations can replace the traditional $j=1$ massless equations, offering a broader theoretical framework.

Findings

Weinberg-Tucker-Hammer equations generalize $j=1$ massless equations

Old equations remain significant as a special case

Possible theoretical consequences are discussed

Abstract

The Weinberg-Tucker-Hammer equations are shown to substitute the common-used $j=1$ massless equations. Meantime, the old equations preserve their significance as a particular case. Possible consequences are discussed.
