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 کاملStudies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
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 کاملStrong phases and D 0 − D 0 mixing parameters
We argue that there could be large, SU(3) violating resonance contributions to D → Kπ decays which would affect the extraction of the D0 −D0 mixing parameters from experiment. Such contributions can induce a large strong phase in the interference between the doubly Cabibbo suppressed and the mixing induced Cabibbo favored contributions to the D0 → K+π− and D0 → K−π+ decays. Consequently, the in...
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...
