Measurement of the CKM Matrix Element |Vub| with B -> rho e ny Decays at BABAR
… fraction for B -> rho e nu decays and the CKM matrix element |Vub| is measured with semileptonic exclusive B-meson decays using approximately 55 million Upsilon(4S) -> BBbar decays collected during the years 2000 and 2001 with the BABAR detector. The result is Br(B0 -> rho- e+ nu) = …

Measurement of the single top quark cross section in the lepton plus jets final state in proton-antiproton collisions at a center of mass energy of 1.96 TeV using the CDF II detector.
… = 172.5 GeV/c^2. In addition, we extract the CKM matrix element value |Vtb| = 0.96 ± 0.09 (stat. + syst.) ± 0.05 (theory) and set a lower limit of |Vtb| > 0.78 at the 95% credibility level.

Measurement of the CP Asymmetry in Semimuonic B Decays Produced in Proton-Antiproton Collisions at Center of Mass Energy= 1.96 TeV
… as a constraint on the complex phase of the CKM matrix element Vts by using the B0 neutral mixing contribution measured at the B factories. We measure the CP violating asymmetry from Bs mixing to be AsSL = 0.020 +/- 0.028.

Measurement of single-top T-channel production using ATLAS data
… to determine the measured cross-section and the CKM matrix element |Vtb|. The cross-section for top and anti-top production is considered separately and the resulting cross-sections are σ t+ = 59 +18 -16 pb for the positive charge channel and σ t- = 33 +13 -12 pb for the negative …

Measurement of the Partial Branching Fraction for Inclusive Semileptonic B Meson Decays to Light Hadrons B->Xu l nu and an Improved Determination of the Quark-Mixing Matrix Element |V_ub|
… statistical and systematic, respectively. The CKM matrix element $|V_{ub}|$ is determined from the measured $\Delta \tilde{\BR}$ using theoretical calculation based on Heavy Quark Expansion. The result is $|V_{ub}| = (4.19 \pm 0.18{}^{+0.26}_{-0.20} {}^{+0.26}_{-0.25}) \times 10^{-3}, where the …

Precision Lattice Calculation of Kaon Decays with Möbius Domain Wall Fermions
… this new result can be used to determine the CKM matrix element Vus to a very high precision when combined with experimental input. The calculation also provides results for various low energy strong interaction constants such as the pseudoscalar decay constants f_K and f_π, and the neutral …
