摘要：
We study the CP violation induced by the interference between two intermediate resonances K*(892)(+) and K*(892)(-) in the phase space of singly-Cabibbo-suppressed decay D-0 -> K+K-pi(0). We adopt the factorization-assisted topological approach in dealing with the decay amplitudes of D-0 -> (KK)-K-+/-*(892)(-/+). The CP asymmetries of two-body decays are predicted to be very tiny, which are (-1.27 +/- 0.25) x 10(-5) and (3.86 +/- 0.26) x 10(-5), respectively, for D-0 -> K+K*(892)(-) and D-0 -> K-K*(892)(+/-), while the differential CP asymmetry of D-0 -> K+K-pi(0) is enhanced because of the interference between the two intermediate resonances, which can reach as large as 3x10(-4). For some NPs which have considerable impacts on the chromomagnetic dipole operator O-8g, the global CP asymmetries of D-0 -> K+K*(892)(-) and D-0 -> K-K*(892)(+) can be then increasedto (0.56 +/- 0.08) x 10(-3) and (-0.50 +/- 0.04) x10(-3), respectively. The regional CP asymmetry in the overlapped region of the phase space can be as large as (1.3 +/- 0.3) x 10(-3).
