Overall determination of the CKM matrix
نویسندگان
چکیده
We discuss the problem of theoretical uncertainties in the combination of observables related to the CKM matrix elements and propose a statistically sensible method for combining them. The overall fit is performed on present data, and constraints on the matrix elements are presented as well as on fBd √ BBd. We then explore the implications of recent measurements and developments: J/ψK S CP asymmetry, ε/ε and B → Kπ branching fractions. Finally, we extract from the overall fit the Standard Model expectations for the rare kaon decays K → πνν̄. ∗Talk given at Heavy Flavours 8, Southampton, UK, 1999

0 5 ) 0 1 3 CKM matrix with lattice QCD – the full determination using recent results –
A full determination of the CKM matrix using recent results from lattice QCD is presented. To extract the CKM matrix in a uniform fashion, I exclusively use results from unquenched lattice QCD as the theory input for nonperturvative QCD effects. All 9 CKM matrix elements and all 4 Wolfenstein parameters are obtained from results for gold-plated quantities, which include semileptonic decay form ...

متن کاملCern European Organization for Nuclear Research the Ckm Matrix and the Unitarity Triangle
This report contains the results of the Workshop on the CKM Unitarity Triangle, held at CERN on 13–16 February 2002, to study the determination of the Cabibbo–Kobayashi–Maskawa (CKM) matrix from the available data of K, D, and B physics. This is a coherent document with chapters covering the determination of CKM elements from tree-level decays and Kand B-meson mixing and the global fits of the ...
متن کاملGlobal fit to CKM data
We present updated results for the CKM matrix elements from a global fit to flavour physics data within the standard model theoretical context. We emphasise recent improvements on the determination of the CKM parameters λ and A as well as on the angle γ of the unitarity triangle.
متن کاملTHE FIRST TWO GENERATIONS - c The Cabibbo
The way in which an exact determination of the CKM matrix elements tests the Standard Model is demonstrated by a two generation example. The determination of matrix elements from meson semi-leptonic decays is explained, with an emphasis on the respective reliability of quark level and meson level calculations. The assumptions involved in the use of loop processes are described. Finally, the sta...
