We perform a new numerical analysis of hyperon semileptonic decays emphasizing the systematic uncertainties. The poor understanding of SU(3) symmetry breaking effects at second order in the vector form factor translates into a large error of |Vus|. Using our determination |Vus| = 0.226 ยฑ 0.005 toget
We report several recent updates from the BABAR Collaboration on the matrix elements |V cb |, |V ub |, and |V td | of the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing matrix, and the angles ฮฒ and ฮฑ of the unitarity triangle. Most results presented here are using the full BABAR ฮฅ(4S) data set.
