D 0 − D 0 Mixing
The main challenge in the Standard Model calculation of the mass and width difference in D −D mixing is to estimate the size of SU(3) breaking. We prove that mixing occurs in the Standard Model only at second order in SU(3) violation. We calculate SU(3) breaking due to phase space effects, and find that it can naturally give rise to a width difference ∆Γ/2Γ ∼ 1%, potentially reducing the sensit...
متن کاملA Determination of the CKM - angle α using Mixing - induced CP Violation in the Decays B d → π + π − and B d → K 0 K̄ 0 ∗ Andrzej
We present a method of determining the CKM-angle α by performing simultaneous measurements of the mixing-induced CP asymmetries of the decays Bd → ππ and Bd → KK̄. The accuracy of our approach is limited by SU(3)-breaking effects originating from b̄ → d̄ss̄ QCD-penguin diagrams. Using plausible power-counting arguments we show that these uncertainties are expected to be of the same order as those a...

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

متن کاملSearch for D 0 −D 0 Mixing CLEO Collaboration
We report on a search for D0−D0 mixing made by a study of the ‘wrong-sign’ process D →K+π−. The data come from 9.0 fb of integrated luminosity of ee collisions at √ s ≈ 10GeV, produced by CESR and accumulated with the CLEO II.V detector. We measure the time-integrated rate of the ‘wrong-sign’ process D → Kπ, relative to that of the Cabibbo-favored process D0→K+π−, to be Rws = (0.34 ± 0.07 ± 0.0...
