Description
We present the status of ongoing work to extract pseudoscalar and vector decay constants for $B^{(*)}$, $B_s^{(*)}$ and $B_c^{(*)}$ mesons and determine phenomenologically interesting ratios such as $f_{B_s}/f_B$ or $f_{B^*}/f_B$. Our results extrapolated to physical quark masses and the continuum are compared to predictions by other lattice collaborations and QCD sum rules, and are used to test heavy quark symmetry relations.
