Precision determination of Bc and Bc* meson decay constants from lattice QCD
Abstract
We present a lattice QCD study of heavy-heavy meson decay constants using the 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 Bc systems. Preliminary results are presented for the decay constants of the Bc, Bc*, ηc, ηb, and Υ mesons.
