Precision tests of the Standard Model with leptonic and semileptonic kaon decays
This paper presents the analysis of leptonic and semileptonic kaon decays data done by the FlaviaNet Kaon Working group, as described in [1]. Data include all recent results by BNL-E865, KLOE, KTeV, ISTRA+, and NA48. Experimental results are critically reviewed and combined, taking into account theoretical (both analytical and numerical) constraints on the semileptonic kaon form factors. We rep...
متن کاملPrecision tests of Standard Model with leptonic and semileptonic kaon decays
Till the middle of 2004 it appeared that the unitarity relation |Vud| + |Vus|+ |Vub| = 1 might not hold at the 2.3σ level. At that time, however, |Vus| was inferred from old experimental data. Since then, a large experimental and theoretical effort has been invested leading to a removal of the problem. Thanks to the new and improved measurements by BNL-E865, KLOE, KTeV, ISTRA+ and NA48, theKl3 ...
متن کاملRare Kaon Decays – Overview
The theory of rare K decays is reviewed, emphasizing short-distance processes and the prospects to probe the physics of flavour. A brief overview of the subject is presented, along with a more detailed discussion of the theory of K → πνν̄ decays. Invited Talk presented at KAON 2001 International Conference on CP Violation, Pisa, 12-17 June 2001
متن کاملRadiative Semileptonic Kaon Decays
We evaluate the matrix elements for the radiative kaon decays K → lνlγ, lνll l and K → πlνlγ (l, l = e, μ) to next-to-leading order in chiral perturbation theory. We calculate total rates and rates with several kinematical cuts and confront the results with existing data. Measurements at future kaon facilities will allow for a more detailed comparison between theory and experiment. † Address af...
متن کاملKaon Decays and Vus
Unitarity for the first row of the quark mixing matrix appears to be fully satisfied by the value of V us obtained from recent new measurements of kaon semileptonic decay rates.
