B Decays on the Lattice
B decay phenomenology is a rapidly growing area of particle physics, as we expect that the precise measurements of various B meson decays provide rich information of the Standard Model and the physics beyond it. Following the successful CLEO, LEP and CDF experiments, the next generation B factories (BaBar and Belle) have just started operation, and other experimental projects will follow. Latti...
متن کاملSemileptonic B decays into higher charmed resonances.
We apply HQET to semi-leptonic B meson decays into a variety of excited charm states. Using three realistic meson models with fermionic light degrees of freedom, we examine the extent that the sum of exclusive single charmed states account for the inclusive semi-leptonic B decay rate. The consistency of form factors with the Bjorken and Voloshin sum rules is also investigated.
متن کاملSemileptonic decays B\pln and D\pln from lattice QCD
We present a lattice QCD calculation of the form factors and differential decay rates for semileptonic decays of the heavy-light mesons B and D to the final state pln . The results are obtained with three methodological improvements over previous lattice calculations: a matching procedure that reduces heavy-quark lattice artifacts, the first study of lattice-spacing dependence, and the introduc...

Resonances from J / Ψ and Ψ ′ Decays
The Institute of High Energy Physics at Beijing runs an electron-positron collider (BEPC) with a general purpose solenoidal detector, the Beijing Spectrometer (BES)[1], which is designed to study exclusive final states in ee annihilations at the center of mass energy from 3000 to 5600 MeV. In this energy range, the largest cross sections are at the J/Ψ(3097) and Ψ(3686) resonant peaks. At prese...
