This corresponds to about 3 million D0-anti-D0 pairs from which we select 1260 tagged candidates with a background of roughly 6%. We find that S-wave features dominate the PI0 PI0 axis of the Dalitz plot, contributing about one-third of the total decay rate, while the K*(892) is the dominant K0S PI0 contribution. Using three tag modes and correcting for quantum correlations we determine that the D0 to K0S PI0 PI0 branching ratio is 1.059% with a statistical uncertainty of 0.049% and a systematic uncertainty of 0.050%. 2010-5 Item withdrawn by Mark Zulauf (zulauf@illinois.edu) on 2010-04-15T12:47:52Z Item was in collections: University of Illinois Theses & Dissertations (ID: 1) No. of bitstreams: 2 Lowrey_Norman.tex: 274388 bytes, checksum: 9eb015a3b4a4338159bc5abff9d241de (MD5) Lowrey_Norman.pdf: 9293059 bytes, checksum: 9649ebd58b8dde4b4f4b625312c39d93 (MD5) Made available in DSpace on 2010-05-19T18:33:14Z (GMT).
