| 英文摘要 | We study the two-body hadronic D -> PV decays, where P (V) denotes a pseudoscalar (vector) meson, in the factorization- assisted topological- amplitude approach proposed in our previous work. This approach is based on the factorization of short- distance and long- distance dynamics into Wilson coefficients and hadronic matrix elements of four-fermion operators, respectively, with the latter being parametrized in terms of several nonperturbative quantities. We further take into account the rho-omega mixing effect, which improves the global fit to the branching ratios involving the rho(0) and omega mesons. Combining short- distance dynamics associated with penguin operators and the hadronic parameters determined from the global fit to branching ratios, we predict direct CP asymmetries. In particular, the direct CP asymmetries in the D-0 -> K-0(K) over bar*(0), K-0(K) over bar*(0) -> pi(+) rho(0), and D-s(+) -> K+omega, K+phi decays are found to be of O(10(-3)), which can be observed at the LHCb and future Belle II experiment. We also predict the CP asymmetry observables of some neutral D meson decays. |
