Behaviour of Charged Spinning Massless Particles
We review some properties of a relativistic classical massless charged particle with 9 spin interacting with an external electromagnetic field. We give in particular a proper definition 10 of kinetic energy and total energy, the latter being conserved when the external field is stationary. 11 We find that the particle’s velocity may differ from c as a result of the spin electromagnetic field 12...
متن کاملThe New Charged Massless States of Quantum Electrodynamics
Quantum Electrodynamics can be formulated as the theory of an antisymmetric tensor gauge field. In this formulation the topologi-cal current of this field appears as an additional source for the electromagnetic field.The topological charge therefore acts physically as an electric charge. The topologically nontrivial, electrically charged, sector contains massless states orthogonal to the vacuum...
متن کاملMassless Classical Electrodynamics
In the direct action form of classical EM we give the equation of motion for a classical massless bare charge without self-interaction in the presence of an external field. That equation permits superluminal speeds and time-reversals, and so is a realization of the Stueckelberg-Feynman view of electrons and positrons as different segments of a single trajectory. We give a particular solution to...
متن کاملMassless quantum electrodynamics with a critical point
Recently, it has been observed that a quantum field theory need not be Hermitian to have a real, positive spectrum. What seems to be required is symmetry under combined parity and time-reversal transformations. This idea is extended to massless electrodynamics, in which the photon couples to the axial-vector current with an imaginary coupling constant. The eigenvalue condition necessary for the...
متن کاملMassless Particles and Fields ”
Free fields of massless particles transforming covariantly under the Poincare group are constructed. The allowed infinite and finite dimensional representations of the Lorentz group are obtained. The wave functions are calculated in these representations in various bases u The commutation rules are computed, and turn out to be non-local for any infinite dimens ional fields. The transformation l...
