A New Measurement of B -> D* Pi Branching Fractions

Creators

Description

The decays Υ(4S) → B(bar B), followed by B → D*π and D* → Dπ, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the D, with reasonably low backgrounds. Using an integrated e+e- luminosity of 3.1 fb-1 accumulated at the Υ(4S) by the CLEO-II detector, we report measurements of Β((bar B)0 → D*+π-) = (2.81 ± 0.11 ± 0.21 ± 0.05) x 10-3 and Β(B- → D*0π-) = (4.34 ± 0.33 ± 0.34 ± 0.18) x 10-3
