Abstract

First observations of the Cabibbo-suppressed decays B0→D+K-π+π- and B-→D0K-π+π- are reported using 35pb -1 of data collected with the LHCb detector. Their branching fractions are measured with respect to the corresponding Cabibbo-favored decays, from which we obtain B(B0→D+K-π+π-)/B(B0→D+π-π+π-)=(5.9±1.1±0.5) ×10-2 and B(B-→D0K-π+π-)/B(B-→D0π-π+π-)=(9.4±1.3±0.9) ×10-2, where the uncertainties are statistical and systematic, respectively. The B-→D0K-π+π- decay is particularly interesting, as it can be used in a similar way to B-→D0K- to measure the Cabibbo-Kobayashi-Maskawa phase γ.
