Relativistic Symmetry Suppresses Quark Spin-Orbit Splitting
arXiv:hep-ph/0002094 · doi:10.1103/PhysRevLett.86.204
Abstract
Experimental data indicate small spin-orbit splittings in hadrons. For heavy-light mesons we identify a relativistic symmetry that suppresses these splittings. We suggest an experimental test in electron-positron annihilation. Furthermore, we argue that the dynamics necessary for this symmetry are possible in QCD.
