Chiral Structure of Particles Bound by Magnetic Forces

Aims/ objectives: Particle bound states exist only as microscopic systems in form of atomic and subatomic particles. An interesting class of these objects are particles bound by magnetic forces, which exhibit the particular property of chirality (handedness, which is not parity symmetric). These particles are discussed in quantum field theory based on a QED like Lagrangian with fermion and boson fields, in which about ten boundary conditions can be defined. With four (but effectively two) adjustable parameters only, this leads to a stringent test of the special mathematical structure of the underlying eld theory.

A first kind of these particles are leptons, e, μ, τ and neutrinos. With an additional quantum condition the radii of charged leptons can be deduced. Other systems of magnetic binding may be found in atoms, a first example being weakly bound H-atoms, which may be the origin of gravitation.
