On the Law of Conservation of Heavy Particles

  • E. P. Wigner
Part of the The Collected Works of Eugene Paul Wigner book series (WIGNER, volume B / 6)


The purpose of this note is to trace in more detail the consequences of treating the conservation law for heavy particles1 on a par with the conservation law for electric charges. It is thus an attempt to guess at the properties of particles as yet unknown and their interactions, and therefore speculative. However, it does not attempt a classification of elementary particles similar to that proposed recently by several writers, in particular, A. Pais.2 In this regard it is somewhat more conservative.
