Precision Determination of V_ub at an e+ e- B Factory
ArXiv hep-ex/0203015 (2002)
Abstract:
Current methods of determining V_ub are dominated by theoretical uncertainties. We present Monte Carlo simulations of three promising methods of determining V_ub with small theoretical and experimental errors. We find that with data samples of order 1,000 fb-1 the B factories will attain combined experimental errors of a few % on V_ub, much smaller than the theoretical errors associated with new inclusive methods. Lattice QCD offers the promise of rate calculations of exclusive semileptonic decays with errors of a few %. A data sample of order 10,000 fb-1, beyond the capabilities of the current B factories, may be required to achieve an experimental error on the exclusive rate comparable to the theoretical error.First measurement of Γ(D*+) and precision measurement of mD*+-mD0

Report of Snowmass 2001 Working Group E2 : Electron-positron Colliders from the $φ$ to the Z
ArXiv hep-ex/0201047 (2002)
Abstract:
We report on the status and plans of experiments now running or proposed for electron-positron colliders at energies between the $\phi$ and the Z. The $e^{+}e^{-}$ B and charm factories we considered were PEP-II/BABAR, KEKB/Belle, superKEK, SuperBABAR, and CESR-c/CLEO-c. We reviewed the programs at the $\phi$ factory at Frascati and the proposed PEP-N facility at Stanford Linear Accelerator Center. We studied the prospects for B physics with a dedicated linear collider Z factory, associated with the TESLA high energy linear collider. In all cases, we compared the physics reach of these facilities with that of alternative experiments at hadron colliders or fixed target facilities.Correlated inclusive ΛΛ̄ production in e +e- annihilations at √s∼10.5 GeV
