Spinning Relativistic Particles in External Fields
arXiv:0801.1881
Abstract
The motion of spinning relativistic particles in external electromagnetic and gravitational fields is considered. A simple derivation of the spin interaction with gravitational field is presented. The self-consistent description of the spin corrections to the equations of motion is built with the noncovariant description of spin and with the usual, ``naive'' definition of the coordinate of a relativistic particle.
