Abstract

First observations of the Cabibbo-suppressed decays B¯ 0 → D +K -π +π - and B - → D 0K -π +π - are reported using 35 pB -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(B¯ 0→ D +K -π +π -)/B(B¯ 0→D +π -π +π -)=(5.9±1.1±0.5)×10 -2 and B(B -→D 0K -π +π -)/B(B -→ D 0π -π +π -)=(9.4±1.3±0.9)×10 -2, where the uncertainties are statistical and systematic, respectively. The B - → D 0K -π +π - decay is particularly interesting, as it can be used in a similar way to B - → D 0K - to measure the Cabibbo-Kobayashi-Maskawa phase γ.
