Measurements of Rare B Meson Decays at Belle
نویسنده
چکیده
We report recent measurements of rare B meson decays by the Belle collaboration including branching fractions and time-independent partial-rate asymmetries. Emphasis is placed on the penguin mediated b → s transition, particularly, the recent discovery of the leptonic penguin decays, b → sll, in both semi-inclusive and exclusive channels. Comparisons are made between experimental results and standard model predictions for several penguin mediated modes. We also report new measurements of B → ωlν and B̄0 → D s π + that are important for determining the CKM matrix element |Vub|.

Study of Rare B Meson Decays at Belle
In this paper, we briefly review results on rare decays of B mesons from the Belle experiment, based on 10.4 fb−1 data collected on the Υ(4S) resonance. The topics include measurements of Cabibbo suppressed decays B → D(∗)K(∗), charmless twobody decays B → ππ, Kπ, KK and B → η′h (h = K+, π+,K0), and a search for flavor changing neutral current decays B → K(∗)l+l−. To appear in the Proceedings o...

Measurements of the angles and sides of the unitarity triangle and of the rates of rare B meson decays are crucial for the precise determination of Standard Model parameters and are sensitive to the presence of new physics particles in the loop diagrams. In this paper the recent measurements performed in this area by BABAR and Belle will be presented. The direct measurement of the angle α is fo...

This report summarizes the latest experimental results on radiative and electroweak rare B meson decays. These rare decay processes proceed through the Flavor-Changing-Neutral-Current processes, and thus are sensitive to the postulated new particles in the theories beyond the Standard Model. Experiments at e + e − colliders, Belle, BaBar and CLEO, have been playing the dominant role, while the ...

I present some recent measurements of B meson decay rates to leptonic and charmless hadronic final states, as well as of CP-violation charge asymmetries and other features. I sketch the theoretical frameworks used to predict these, and indicate the level of agreement of the estimates with experiment. INTRODUCTION The dominant channels through which ground-state hadrons containing b quarks decay...
