Research output: Contribution to journalConference article

Abstract

We report recent measurements from LHCb on B(s) → D( s)h(h)(h) decays using ∼35 pb-1 of data collected in 2010. In brief, we measure the following ratios of branching fractions: B(B0 → D+K-)/B(B̄0 → D +π- = 0.0752 ±0.0064 ±0.0026 B(B̄s0 → D0K*0)/ B(B0 → D0ρ0 = 1.39±0. 31±0.17±0.18 B(B̄0 → D+K - π+ π- = 0.052 ±0.009 ± 0.005 B(B0 → D+ π -π+π-)/B(B- → D 0K-π+π-) = 0.096±0.015±0.008 where the uncertainties are statistical and systematic, respectively. The first of these measurements is the most precise to date, and the others are first observations.
