B_(s) → D_(s)h(h)(h) Decays in LHCb

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(B̄_s⁰ → 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.
