A note on the recent Foldy-Wouthuysen transformations for particles of arbitrary spin
J. Jayaraman · Journal of Physics A Mathematical and General · 1975
The authors present a discussion on the recently constructed unitary operator for arbitrary spin, which transforms the Foldy-Wouthuysen Hamiltonian into that of the Weaver, Hammer and Good (WHG) description and demonstrate its incompatibility with preserving the local transformation property of the WHG wavefunction.
