On the Hamiltonian Form of Generalized Dirac Equation for Fermions with Two Mass States
arXiv:hep-ph/0603181
Abstract
Dynamical and non-dynamical components of the 20-component wave function are separated in the generalized Dirac equation of the first order, describing fermions with spin 1/2 and two mass states. After the exclusion of the non-dynamical components, we obtain the Hamiltonian Form of equations. Minimal and non-minimal electromagnetic interactions of particles are considered here.
