The static B∗Bpi coupling, ĝχ, a low energy constant in the leading order heavy meson chiral Lagrangian, is determined using Nf = 2 lattice QCD. We use CLS ensembles with lattice spacings and pion masses down to a = 0.05fm and mpi = 270MeV, and perform combined continuum and chiral extrapolations of our results which have a much better accuracy than previous numbers in the literature. As a by-product, we determine the cou-pling between the first radial excitations in the B and B ∗ channels (ĝ22). Accounting for all uncertainties, which are dominated by the chiral extrapolation, we obtain ĝχ = 0.492(29), while ĝ22 is somewhat smaller. The comparison to a precise quenched computation sug-gests that there is little influence by the sea qua...
