Abstract: A formalism of the classical chiral  kinetic theory in even d+1 dimensions yielding  both the  chiral  anomaly and chiral magnetic effect in external electromagnetic fields will be presented. Fitrst,  the definition of the Berry gauge fields for  Weyl  Hamiltonians in general is recalled. Then employing differential forms, the Hamiltonian methods are extended to  cover the symplectic  forms which are matrix valued in spin space. Within this new formalism a  simple method of finding the path integral measure and the chiral current in the presence of external electromagnetic fields is presented.
