Abstract

A new kinetic equation and Lagrangian of a massive and charged spin-one vector boson is outlined in this paper. Those quantities are derived by exploiting directly the Lorentz group generators including the boson spin. Thereby, the chiral symmetry of the Lorentz transformation is guiding the algebraic calculations. Two associated 4\,x\,4 spin and helicity matrices can be defined, the sum of which give the rotation operator that yields in the presence of an electromagnetic field the boson-spin coupling to the magnetic field. The four polarization vectors of the boson field are calculated and discussed. Moreover, the current density is derived and used to reveal the bosonic nature of the kinetic equations. The energetic stability of the vector boson quantum field is shown. A Pauli equation for the vector boson is derived.
