Description
Using a sample of $(470.9 \pm 2.8) \times 10^6$ B meson pairs, we measure the decay branching fraction ${\mathcal{B}(B^0\to D^{*- }\pi^+ \pi^- \pi^+) = (7.26 \pm 0.11 \pm 0.31) \cdot 10^{-3}}$, where the first uncertainty is statistical and the second uncertainty is systematic. The measurement is 2.4 times more precise than the current world average value. This branching fraction includes singly-charmed $B^0$ decays only and is obtained by removing the dominant doubly-charmed $B^0$ decay contribution from the contaminated branching fraction of $(7.37 \pm 0.11 \pm 0.31) \cdot 10^{-3}$.
