Behaviour of Charged Spinning Massless Particles
We revisit the classical theory of a relativistic massless charged point
particle with spin and interacting with an external electromagnetic field. In
particular, we give a proper definition of its kinetic energy and its total
energy, the latter being conserved when the external field is stationary. We
also write the conservation laws for the linear and angular momenta. Finally,
we find that the particle's velocity may differ from as a result of the
spin---electromagnetic field interaction, without jeopardizing Lorentz
invariance.Comment: PDFtex file, 20 pages, 3 figures Revised version published in
