Exclusive B → Mℓ + ℓ − (M = π, K, ρ, K ∗ ) Decays and Determinations of |Vts | and/or |Vtd/Vts|
We examine the possibility for precise determination of |Vtd| and/or |Vtd/Vts| from the ratios of exclusive decays, (B → ρl+l−)/(B → K∗l+l−) and (B → πl+l−)/(B → Kl+l−). We show that the ratio |Vtd/Vts| can be extracted experimentally with a small theoretical uncertainty from SU(3) breaking effects and hadronic form–factors, if we appropriately constrain kinematical regions of q2. We also give ...

We examine the possibility for precise determination of |Vts| (and |Vtd/Vts|) from the exclusive decays, B → Kl+l−, B → K∗l+l− (and B → πl+l−, B → ρl+l−). We show that the ratio |Vts| can be extracted experimentally with a small theoretical uncertainty from hadronic form–factors, if we appropriately constrain kinematical regions of q2. We also give detailed analytical and numerical results on t...
متن کاملRare Kaon Decays: Progress and Prospects
There is a large overlap in the current physics motivation for investigating B-meson and K-meson decays. The much newer and heavier b quark opens many possibilities for studying interesting decay channels with fascinating phenomenologies of mixing, oscillations, and CP violation. In the past year the promise of revealing the origin of CP violation has begun to be realized in pioneering experime...
متن کاملB Physics B Physics
A summary of the most recent and important measurements in b physics is presented. The production of beauty particles in Z decays, b quark couplings, lifetimes, B-B0 oscillations, semileptonic b decays and studies of the number of charm quarks produced in b decays are reviewed. Extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |Vtd|, |Vcb|, |Vub| and implication for |Vts| are di...
متن کاملCLEO III, A Dectector To Measure Rare B Decays and CP Violation
The symmetric ee collider CESR is undergoing a series of upgrades allowing for luminosities in excess of 2×10cms. The most important goals of the upgrade are precision measurement of standard model parameters Vcb, Vub, Vtd/Vts, fDs, and searching for CP violation and standard model violations in rare B decays. A new detector upgrade, called CLEO III, has started which includes a new silicon-wir...
