Alexandru Proca (1897--1955) the Great Physicist

Abstract

We commemorate 50 years from A. Proca's death. Proca equation is a relativistic wave equation for a massive spin-1 particle. The weak interaction is transmitted by such kind of vector bosons. Also vector fields are used to describe spin-1 mesons (e.g. $\rho$ and $\omega$ mesons). After a brief biography, the paper presents an introduction into relativistic field theory, including Klein-Gordon, Dirac, and Maxwell fields, allowing to understand this scientific achievement and some consequences for the theory of strong interactions as well as for Maxwell-Proca and Einstein-Proca theories. The modern approach of the nonzero photon mass and the superluminal radiation field are also mentioned.
