D -D mixing at BABAR
This article reviews the recent measurement of D-D mixing with the D → Kπ decay channel from the BABAR experiment at the PEP-II B-Factory. Averages from the Heavy Flavor Averaging Group btween this result and a previous result from BELLE are also presented.
متن کاملD 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 کاملLow Energy D+D Reactions in Metal
D+D reactions in various metals were investigated for the deuteron bombardment with bombarding energies at around 150 keV and below 15 keV. Energetic protons andα-particles which can never be attained in the D+D reaction were observed in bombardments with higher energy deuterons. In order to explain the spectra, reaction processes in which three deuterons are involved are considered; sequential...
متن کاملCompilation of D→D Mixing Predictions
We present a compilation of predictions for the amplitudes of D−D mixing. We are not aware of any exhaustive compilation of predictions for the amplitudes for D→D. We have therefore found it helpful to compile, here, those predictions that we have found in a rudimentary search of the literature. Our search has depended upon the SLAC Spires data base, available at the URL: http://www-spires.slac...
متن کامل–D Mixing at BABAR
Mixing among the lightest neutral mesons of each flavor has traditionally provided important information on the electroweak interactions, the CKMmatrix, and the possible virtual constituents that can lead to mixing. Among the long-lived mesons, the D meson system exhibits the smallest mixing phenomena. The B-factories have now accumulated sufficient luminosity to observe mixing in the D system ...
