Abstract
We present a measurement of R B , the ratio of the branching fraction for the rare decay D 0 → K + π − to that for the Cabibbo-favored decay D 0 → K − π + . Charge-conjugate decays are implicitly included. A signal of 2005 ± 104 events for the decay D 0 → K + π − is obtained using the CDF II detector at the Fermilab Tevatron collider. The data set corresponds to an integrated luminosity of 0.35 fb − 1 produced in ¯ p p collisions at √ s = 1.96 TeV . Assuming no mixing, we find R B = [ 4.05 ± 0.21 ( stat ) ± 0.11 ( syst ) ] × 10 − 3 . This measurement is consistent with the world average, and comparable in accuracy with the best measurements from other experiments.
