英文摘要 | The helicity of a free massless relativistic particle, chi(0) = s.P/vertical bar P vertical bar, is generalized, for a particle in an electromagnetic field, to chi = s . p/epsilon where epsilon is energy. Both chi(0) and chi coincide and are conserved for minimal coupling (gyromagnetic ratio g = 0) but are different and neither of them is conserved when the coupling is non-minimal, g not equal 0, generating non-zero effective mass. For a chiral particle with g = 2 in a constant electric field both helicities converge asymptotically to the same value. Helicity is also conserved for minimal gravitational coupling.
