Updated average $f_s/f_d$ $b$-hadron production fraction ratio for 7 TeV $pp$ collisions
Improved knowledge of the branching fraction of the decay $D_{s}^{-} \to K^{+}K^{-}\pi^{-}$ and of the $B$ meson lifetimes has an impact on the measurement of the ratio of $B^{0}$ and $B_{s}^{0}$ meson production cross-sections, $f_{s}/f_{d}$, measured at LHCb. This note reports a new combination...

| description | Improved knowledge of the branching fraction of the decay $D_{s}^{-} \to K^{+}K^{-}\pi^{-}$ and of the $B$ meson lifetimes has an impact on the measurement of the ratio of $B^{0}$ and $B_{s}^{0}$ meson production cross-sections, $f_{s}/f_{d}$, measured at LHCb. This note reports a new combination of the LHCb measurements of $f_s/f_d$, resulting in \mbox{$f_{s}/f_{d} = 0.259 \pm 0.015$}. |
