Recent Charm Results from Fermilab Experiment E791
Abstract
Fermilab experiment E791 studied weak decays of D+, Ds, and D0 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/A1, A2/A1, and A3/A1 in D->K*-l-nu and Ds->phi-l-nu decays; (b) measurement of the difference in decay widths between the two D0/D0-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.
