摘要：

The exact Foldy-Wouthuysen transformation method is generalized here. In principle, it is not possible to construct the exact Foldy-Wouthuysen transformation for any Hamiltonian. The transformation conditions are the same, but the involution operator has a new form. We took a particular example and constructed explicitly the new involution operator that allows one to perform the transformation. We treat the case of the Hamiltonian with 160 possible CPT-Lorentz breaking terms, using this new technique. The transformation was performed, and physics analysis of the equations of motion is shown.
