@ARTICLEBurns:2011jv, author= Burns, T. J., title= P-Wave Spin-Spin Splitting and Meson Loops, journal= The Proceedings of ``XIV International Conference on Hadron Spectroscopy'', year= 2011, month= aug, abstract= In quark potential models the hyperfine splitting of P-wave mesonsis zero in the nonrelativistic limit, a prediction strikingly confirmedby experiment in both charmonia and bottomonia. The result, however,ignores the coupling of bare quarkonia to meson-meson pairs. Thiscoupling causes mass shifts among the states and so could potentiallyspoil the quark model prediction. This turns out not to be the case:in a variety of models the hyperfine splitting remains small despitelarge mass shifts. This is shown to be a generic feature of modelsin which the coupling involves the creation of a light quark pairwith spin-one and the quark spin wavefunctions are conserved.
