The BABAR collaboration measured the decay branching fraction B(B'→D∗-πππ+) =(ι∈l∞∞(stat.)±l 3∂ ∞(syst.)) × ∞l-∂ using a sample of (470.9 ± 2.8) × 106 BB pairs. This measurement will facilitate the measurement of B(B' → D∗- τ+ντ) with τ+ → π+π-π+ντ at hadronic colliders, improving the experimental precision on the normalization branching fraction B(B' → D∗-'π+ π-π+).

Abstract
The BABAR collaboration measured the decay branching fraction B(B'→D∗-πππ+) =(ι∈l∞∞(stat.)±l 3∂ ∞(syst.)) × ∞l-∂ using a sample of (470.9 ± 2.8) × 106 BB pairs. This measurement will facilitate the measurement of B(B' → D∗- τ+ντ) with τ+ → π+π-π+ντ at hadronic colliders, improving the experimental precision on the normalization branching fraction B(B' → D∗-'π+ π-π+).File in questo prodotto:
