Renormalization of Currents for Massive Fermions
A. S. Kronfeld, S. Hashimoto
The renormalization of vector and axial-vector currents for massive fermions (in the ``Fermilab formalism'') is discussed. We give results for non-degenerate masses, which are need…
B -> D l nu form factors and the determination of |Vcb|
S. Hashimoto, A. X. El-Khadra, A. S. Kronfeld +3
The zero recoil limit of the B -> D l nu form factors is calculated on the lattice, which provides a model-independent determination of |Vcb|. Considering a ratio of form factors,…
Estimated Errors in |Vcd|/|Vcs| from Semileptonic D Decays
J. N. Simone, A. X. El-Khadra, S. Hashimoto +3
We estimate statistical and systematic errors in the extraction of the CKM ratio |Vcd|/|Vcs| from exclusive D-meson semileptonic decays using lattice QCD and anticipated new experi…
Three Electroweak Results from Lattice QCD
Andreas S. Kronfeld
Quantum chromodynamics is needed to understand quarks and, hence, to determine the quarks' Yukawa couplings from experimental measurements. As a short illustration, the results of…
