Precision model-independent bounds from a global analysis of form factors
Abstract
We present a model-independent global analysis of hadronic form factors for the semileptonic decays that exploits lattice-QCD data, dispersion relations, and heavy-quark symmetries. The analysis yields predictions for the relevant form factors, within quantifiable bounds. These form factors are used to compute the semileptonic ratios $$R(H_c)$$ and various decay-product polarizations. In particular, we find $$R(D^{\ast}_s)$$ = 0.20(3) and $$R(J/\psi)$$ = 0.25(3), predictions that can be compared to results of upcoming LHCb measurements. In developing this treatment, we obtain leading-order nonrelativistic QCD results for the nonzero-recoil relations between the $$B^+_c → \{J/\psi, η_c\}$$ form factors.
