Understand

By using the Highly Improved Staggered Quark formalism to handle charm, strange and light valence quarks in full lattice QCD, and NRQCD to handle bottom valence quarks we are able to determine accurately ratios of the B meson vector-pseudoscalar mass splittings, in particular, (m(B*_c)-m(B_c))/(m(B*_s)-m(B_s)).

We find this ratio to be 1.15(15), showing the `light' quark mass dependence of this splitting to be very small.
Hence we predict m(B_c*) = 6.330(7)(2)(6) GeV where the first two errors are from the lattice calculation and the third from existing experiment.
This is the most accurate prediction of a gold-plated hadron mass from lattice QCD to date.
