Measurement of the ratio of branching fractions B(D(0)-> K(+)pi(-))/B(D(0)-> K(-)pi(+)) using the CDF II detector

Abstract:

We present a measurement of R B, the ratio of the branching fraction for the rare decay D0→K +π - to that for the Cabibbo-favored decay D0→K -π +. Charge-conjugate decays are implicitly included. A signal of 2005±104 events for the decay D0→K +π - is obtained using the CDF II detector at the Fermilab Tevatron collider. The data set corresponds to an integrated luminosity of 0.35fb -1 produced in p̄p collisions at √s=1.96TeV. Assuming no mixing, we find R B=[4.05±0. 21(stat)±0.11(syst)]×10 -3....
