Title: First observation of the decays B(0) D(+)K(-)pi(+)pi(-) and B(-) D(0)K(-)pi(+)pi(-)
Abstract:First observations of the Cabibbo-suppressed decays B(0) D(+)K(-)pi(+)pi(-) and B(-) D(0)K(-)pi(+)pi(-) are reported using 35 pb(-1) of data collected with the LHCb detector. Their branching fractions...First observations of the Cabibbo-suppressed decays B(0) D(+)K(-)pi(+)pi(-) and B(-) D(0)K(-)pi(+)pi(-) 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(-)pi(+)pi(-))/B(B(0) D(+)pi(-)pi(+)pi(-))=(5.9±1.1±0.5)*10(-2) and B(B(-) D(0)K(-)pi(+)pi(-))/B(B(-) D(0)pi(-)pi(+)pi(-))=(9.4±1.3±0.9)*10(-2), where the uncertainties are statistical and systematic, respectively. The B(-) D(0)K(-)pi(+)pi(-) decay is particularly interesting, as it can be used in a similar way to B(-) D(0)K(-) to measure the Cabibbo-Kobayashi-Maskawa phase gamma.Read More
