Recent Charm Results from Fermilab Experiment E791

Fermilab experiment E791 studied weak decays of D+, D_s, and D^0 mesons produced in collisions of 500 GeV/c negative pions with Pt and C targets. The experiment collected over 200,000 fully reconstructed charm decays. Four recent results are discussed here: (a) measurement of the form factor ratios V/A_1, A_2/A_1, and A_3/A_1 in D->K*-l-nu and Ds->phi-l-nu decays; (b) measurement of the difference in decay widths $\Delta\Gamma$ between the two D^0/D^0-bar mass eigenstates; (c) search for rare and forbidden D decays to dilepton final states; and (d) search for a ``Pentaquark,'' a bound state of c-bar-suud.Comment: 8 pages, 2 figures, contribution to XXXIVth Rencontres de Moriond, Electroweak Interactions and Unified Theories, March, 199

Rare hadronic B decays: probing deeper into the Standard Model

We present recent results from the Belle experiment on rare hadronic B meson decays. The results are based on a 78 fb^{-1} data sample and consist of branching fractions, CP asymmetries, and polarization amplitudes. The decays studied include two-body pseudoscalar-pseudoscalar final states (B -> pi pi, K pi, KK, and D^0 K^\pm); pseudoscalar-vector final states (B -> omega pi, omega K, and phi K); and vector-vector final states (B -> phi K* and rho^+ rho^0).Comment: 12 pages, 8 figures, 7 tables, recent results from the Belle experiment.
