First observations of the Cabibbo-suppressed decays $\bar{B}^0\to D^{+}K^{-}\pi^{+}\pi^{-}$ and $B^{-}\to D^{0} K^{-}\pi^{+}\pi^{-}$
Using 35 pb$^{-1}$ of data collected in $pp$ collisions at $\sqrt{s}$ = 7 TeV by the LHCb experiment, we report first observations of the Cabibbo-suppressed decays $\bar{B}^0\to D^{+}K^{-}\pi^{+}\pi^{-}$ and $B^{-}\to D^{0} K^{-}\pi^{+}\pi^{-}$, and measure their branching fractions relative to the...
