Description
We present lattice QCD results for semileptonic form factors of the decays
B_c -> eta_c l v and B_c -> Jpsi l v over the full q^2 range,
using both improved non-relativistic QCD (NRQCD) and fully relativistic (HISQ) formalisms. These can be viewed as prototype calculations for pseudoscalar to pseudoscalar and pseudoscalar to vector decays involving a b -> c transition. In
particular we can use information from the relativistic computations to fix the NRQCD current normalisations, which can then be used in improved computations of decays such as B -> D l v and B -> D^* l v.
