  • We present a selection of recent results from studies of rare hadronic B decays based on a sample of 232 million B{bar B} pairs, corresponding to an integrated luminosity of 211 fb{sup -1}, which were recorded with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage ring.
  • We present preliminary inclusive branching fraction measurements of {tau}{sup -} {yields} h{sup -}h{sup -}h{sup +}{nu} (h = {pi} or K) and {tau}{sup -} K{sup -}{pi}{sup 0}{nu} decay modes using a sample of {tau}-pair events collected by the BABAR detector at the SLAC PEP-II asymmetric e{sup +}e{sup -} storage ring. The branching fractions of {tau}{sup -} {yields} {pi}{sup -}{pi}{sup -}{pi}{sup +}, {tau}{sup -} {yields} K{sup -}{pi}{sup -}{pi}{sup +}{nu}, and {tau}{sup -} {yields} K{sup -}{pi}{sup -}K{sup +}{nu} are measured with higher precision than previously published results and the inclusive branching fraction {tau}{sup -} {yields} K{sup -}K{sup -}K{sup +}{nu} is measured for themore » first time. In addition, the first measurement of the branching fraction {tau}{sup -} {yields} {pi}{sup -}{phi}{nu} and the measurement of the branching fraction {tau}{sup -} {yields} K{sup -}{phi}{nu} are determined by means of a binned maximum likelihood fit to the K{sup +}K{sup -} invariant mass distribution. These branching fractions are extracted by means of a migration matrix that accounts for the cross contamination between the {tau}{sup -} {yields} h{sup -}h{sup -}h{sup +}{nu} modes. The preliminary {tau}{sup -} {yields} K{sup -}{pi}{sup 0}{nu} branching fraction and invariant mass distributions are also presented in this paper.« less
  • We present a measurement of the absolute branching fractions {Beta}(D{sub s}{sup -} {yields} {mu}{sup -}{bar {nu}}{sub {mu}}) and {Beta}(D{sub s}{sup -} {yields} {tau}{sup -}{bar {nu}}{sub {tau}}) and of the D{sub s} decay constant, f{sub D{sub s}}. They also obtain an upper limit on {Beta}(D{sub s}{sup -} {yields} e{bar {nu}}{sub e}). Then they present results on Dalitz plot analysis of D{sub s}{sup +} decays to K{sup +}K{sup -}{pi}{sup +} and {pi}{sup +}{pi}{sup -}{pi}{sup +}. The {pi}{sup +}{pi}{sup -} and K{sup +}K{sup -} S-waves are extracted by a model-independent partial wave analysis. Finally they measure relative branching fractions of D{sub s}{sup +}more » {yields} {pi}{sup +}{pi}{sup -}{pi}{sup +}, D{sub s}{sup +} {yields} K{sup +}K{sup -}K{sup +}, and D{sub s}{sup +} {yields} K{sup +}K{sup +}{pi}{sup -} relative to D{sub s}{sup +} {yields} K{sup +}K{sup -}{pi}{sup +}. All the results make use of data collected by the BABAR detector at the PEP-II storage rings at SLAC.« less
