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.", "revisions": [ { "version": "v1", "updated": "1999-08-18T02:55:15.000Z" } ], "analyses": { "keywords": [ "fermilab experiment e791", "charm results", "form factor ratios", "dilepton final states", "weak decays" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 505701, "adsabs": "1999hep.ex....8054S" } } }
