Heavy-light meson decay constants and hyperfine splittings with the heavy-HISQ method

Kerr A. Miller, Judd Harrison, Christine T. H. Davies +1

We compute ratios between the vector and pseudoscalar, and tensor and vector decay constants, and between hyperfine splittings for $D_{(s)}^{(\ast )}$ and $B_{(s)}^{(\ast )}$ mesons. We us…
