Abstract

Within the covariant Lagrangian formalism the equations of motion for spin 1/2 particles with polarizabilities in the electromagnetic field have been obtained. The resulting equations of motion are consistent with the Compton scattering amplitude, which follows from the low-energy theorems. The covariant Lagrangian is agreed with the low-energy definition in Lagrangian formalism. The canonical and metric tensors of particles with polarizabilities interacting with the electromagnetic field have been constructed and have been analyzed at the phenomenological level. In the particle rest system, the energy density of the interaction of the particle with the polarizabilities and the electromagnetic field have been obtained.
