Available in PDF, EPUB and Kindle. Book excerpt: We measure CP-violating asymmetries of neutral charmed mesons in the modes D° → K−K and D° →?−?+ with the highest precision to date by using D° → K−?+ decays to correct detector asymmetries. An analysis of 385.8 fb−1 of data collected with the BaBar detector yields values of a{sup KK}{sub CP} = (0.00 ± 0.34 (stat.) ± 0.13 (syst.))% and a{sup?{pi}}{sub CP} = ( -0.24 ± 0.52 (stat.) ± 0.22 (syst.))%, which agree with Standard Model predictions.
