The fit result for the hyperfine splitting from the action with spin-dependent four-quark operators. The two error bars are as follows: the smaller band includes statistics and scale setting, and the larger band includes correlated errors from missing radiative corrections to and quark mass tuning errors. The grey band is our final result, including all systematic errors. Also shown are the pure results, which are not included in the fit, and the PDG average [2].
The fit result for the hyperfine ratio from the action with spin-dependent four-quark operators. Also shown are the pure results, which are not included in the fit, and the results from Belle and Dobbs et al. [5, 6].
Comparison of our result (top) with other lattice calculations [18, 20, 21, 23, 35] and experimental [1–6] results for the hyperfine splittings. The hyperfine splitting is on the left and the on the right. The value plotted for the earlier HPQCD result has been corrected for the , error and the value uses the 2013 PDG average for to extract from the ratio given in that paper. Meinel quotes two results for , normalizing the result using either the hyperfine or the tensor splitting. The results are taken as given in Ref. [23].
