SO(3) is subgroup of Poicare group.Does Relativistic Quantum Mechanics obey rotational symmetry.If it is,why we do not still keep the non-relativistic concept of angular momentum(orbit angular momentum plus spin) for relativistic concept of angular momentum,but we instead replace the concept by Pauli-Plebanski vector for relativistic regime?Because if it is obeyed SO(3) the angular momentum still conserves despite it is non-covariant with Lorentz tranformation.(adsbygoogle = window.adsbygoogle || []).push({});
