Description

We present a lattice QCD study of heavy-heavy meson decay constants using HISQ gauge ensemble generated by the MILC Collaboration. Employing the HISQ action for both charm and bottom valence quarks tuned to their physical masses, we determine pseudoscalar, vector, and tensor decay constants for heavy quarkonium and $B_c$ systems. Preliminary results are presented for the decay constants of the $B_c$, $B_c^\star$, $\eta_c$, $\eta_b$, and $\Upsilon$ mesons.
