Using a sample of (470.9±2.8)x10^6 BBbar pairs, we measure the decay branching fraction B(B0-->D*-pi+pi-pi+)=(7.26±0.11±0.31)x10^-3, where the first uncertainty is statistical and the second is systematic. Our measurement will be helpful in studies of lepton universality by measuring B(B0-->D*-tau+nu) using tau-->pi+pi-pi+nubar decays, normalized to B(B0-->D*-pi+pi-pi+).

Abstract
Using a sample of (470.9±2.8)x10^6 BBbar pairs, we measure the decay branching fraction B(B0-->D*-pi+pi-pi+)=(7.26±0.11±0.31)x10^-3, where the first uncertainty is statistical and the second is systematic. Our measurement will be helpful in studies of lepton universality by measuring B(B0-->D*-tau+nu) using tau-->pi+pi-pi+nubar decays, normalized to B(B0-->D*-pi+pi-pi+).File in questo prodotto:
