Description

We compute the hyperfine splitting in a heavy quarkonium composed of different flavors in next-to-leading logarithmic approximation using the nonrelativistic renormalization group. We predict the mass difference of the vector and pseudoscalar charm-bottom mesons to be M(Bc*)-M(Bc)=65 ± 24(th)-16+19(δαs) MeV. (orig.)
