Splitting the Kemmer-Duffin-Petiau equations

Abstract:
We study internal structure of the Kemmer-Duffin-Petiau equations for spin-0 and spin-1 mesons. We demonstrate, that the Kemmer-Duffin-Petiau equations can be splitted into constituent equations, describing particles with definite mass and broken Lorentz symmetry. We demonstrate that the constituent equations are closely related with the Dirac equation. The splitting of the KDP equations is also interpreted in the infinite momentum frame. The resulting picture is compared wih SU(3) classification of mesons.
