Book Description
The authors measure the absolute branching fraction for D° → K−? using partial reconstruction of {bar B}° → D*+Xl−{bar {nu}}{sub {ell}} decays, in which only the charged lepton and the pion from the decay D*+ → D°?+ are used. Based on a data sample of 230 million B{bar B} pairs collected at the?(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, they obtain?(D° → K−?+) = (4.007 ± 0.037 ± 0.070)%, where the first error is statistical and the second error is systematic.

Book Description
We present branching fraction measurements of charged and neutral B decays to D{pi}{sup -}, D*{pi}{sup -} and D**{pi}{sup -} with a missing mass method, based on a sample of 231 million {Upsilon}(4S) {yields} B{bar B} pairs collected by the BABAR detector at the PEP-II e{sup +}e{sup -} collider. One of the B mesons is fully reconstructed and the other one decays to a reconstructed charged {pi} and a companion charmed meson identified by its recoil mass, inferred by kinematics. Here D** refers to the sum of all the non-strange charm meson states with masses in the range 2.2-2.8 GeV/c{sup 2}.

Book Description
The authors present measurements of the branching fractions for the charmless two-body decays B° →??− and B° → K+?−, and a search for the decay B° → K+K−. They include the effects of final-state radiation from the daughter mesons for the first time, and quote branching fractions for the inclusive processes B° → h+h'−n?, where h and h' are pion or kaons. The maximum value of the sum of the energies of the n undetected photons, E{sub {gamma}}{sup max}, is mode-dependent. Using a data sample of approximately 227 million?(4S) → B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy e+e− collider at SLAC.

Book Description
The authors present a measurement of R{sub B}, the ratio of the branching fraction for the rare decay D° → K?− to that for the Cabibbo-favored decay D° → K−?+. Charge conjugate decays are implicitly included. A signal of 2005 ± 104 events for the decay D° → K+?− 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 {bar p}p collisions at √s = 1.96 TeV. Assuming no mixing, they find R{sub B} = [4.05 ± 0.21(stat) ± 0.11(syst)] x 10−3. This measurement is consistent with the world average, and comparable in accuracy with the best measurements from other experiments.
