Book Description
This thesis presents a Dalitz plot analysis of D0 to K0S PI0 PI0 using the CLEO-c data set of 818 inverse picobarns of positron-electron collisions accumulated at center-of-mass energy 3.77 GeV. 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%.

Book Description
This dissertation presents a measurement of CP asymmetries and branching fractions for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 88 million?(4S) → B{bar B} decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B factory located at the Stanford Linear Accelerator Center. A fit to kinematic, topological, and particle identification information measures the charge-averaged branching fractions?(B° →??−) = (4.7 ± 0.6 ± 0.2) x 10−6 and?(B° → K+?−) = (17.9 ± 0.9 ± 0.7) x 10−6; the 90% confidence level upper limit?(B° → K+K−)

Book Description
We present preliminary results of maximum-likelihood Dalitz plot analyses performed by the BABAR Collaboration of the charmless hadronic decays B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0}, B{sup +} {yields} K{sup +}{pi}{sup -}{pi}{sup +}, and B{sup +} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup +}. We report inclusive decay rates, as well as fractions and phases for intermediate resonant decays. We also report CP-violating charge asymmetries for intermediate resonant decays of neutral B mesons.
