Abstract

The first flavor-tagged amplitude analysis of the decay D0 to the self-conjugate final state K+K−π+π− is presented. Approximately 3000 signal decays are selected from data acquired by the CLEO II.V, CLEO III, and CLEO-c detectors. The three most significant amplitudes, which contribute to the model that best fits the data, are ϕρ0, K1(1270)±K∓, and nonresonant K+K−π+π−. Separate amplitude analyses of D0 and D¯0 candidates indicate no CP violation among the amplitudes at the level of 5% to 30% depending on the mode. In addition, the sensitivity to the CP-violating parameter γ/ϕ3 from a sample of 2000 B+→D˜0(K+K−π+π−)K+ decays, where D˜ is a D0 or D¯0, collected at LHCb or a future flavor facility, is estimated to be (11.3±0.3)° using the favored model.Received 27 January 2012DOI:https://doi.org/10.1103/PhysRevD.85.122002© 2012 American Physical Society
