A measurement of the ratio of branching fractions: $\frac{\mathcal{B}(B^{\pm}\rightarrow D K^{\pm})}{\mathcal{B}(B^{\pm}\rightarrow D\pi^{\pm})}$ for $D\rightarrow K\pi$, $KK$, $K\pi\pi\pi$ and $K^0_S\pi\pi$
Using the 36.5~pb$^{-1}$ of data collected by the LHCb experiment in 2010, the ratio of two $B_u$ hadronic branching fractions: ${\cal B}(B^{\pm}\rightarrow D K^{\pm})\ /\ {\cal B}(B^{\pm}\rightarrow D \pi^{\pm})$ is measured for events in which the $D$ meson is reconstructed in one of four final st...
