Recent results on rare kaon decays are reviewed and prospects for future experiments are discussed.
Till the middle of 2004 it appeared that the unitarity relation Vud^2+Vus^2+Vub^2=1 might not hold at the 2.3sigma level. At that time, however, Vus was inferred from old experimental data. Since then, a large experimental and theoretical…
In the last few years a significant progress in the kaon physics has been made by three experiments - KLOE, KTeV and NA48. The reflection of their results to the extraction of the parameter Vus of the CKM matrix is presented. The obtained…
The most precise determination of Vus comes from semileptonic kaon decays. We have measured with the KLOE detector at DAFNE, the Frascati phi-factory, all the experimental inputs to Vus for both neutral and charged kaons. Using our results…
We briefly review the current status of the determination of |V_{us}| and |V_{ud}|, with particular attention to the latest experimental and theoretical developments on |V_{us}| since the first CKM Workshop.
Some theoretical results on V_ub and V_cb determinations from inclusive decays of b hadrons are highlighted.
I review recent developments in rare and radiative kaon decays from the theory side, with emphasis on those modes that are actively analyzed by the experimental collaborations.
A brief review of current results on rare kaon decays, particularly the charged and neutral K-> pi nu nubar channels, is presented along with prospects for future measurements.
Predictions for decay rates and distributions for $\tau$ decays into final states with kaons are discussed and compared with recent measurements. Special emphasis is put on new constraints for the vector current contribution in the $KK\pi$…
Recent results on rare kaon and pion decays are reviewed and prospects for future experiments are discussed
The current status of the study of rare kaon decays is reviewed. Future prospects are discussed.
Recent experimental results on hadronic tau decays into strange particles by the OPAL collaboration are employed to determine V_us and m_s from moments of the invariant mass distribution. Our results are V_us = 0.2208+-0.0034 and m_s(2 GeV)…
The present status of Kaon physics is summarized from a theory point of view. Focus is laid on $\Delta S=2$, $\Delta S=1$ as well as on rare Kaon decays, where progress has been made for instance in the case of $\varepsilon_K$ and $K_S\to…
Recent results on charged rare kaon decays from the NA48/2 Collaboration and on neutral kaon decays from the KLOE Collaboration will be reviewed.
We review the status and future prospects of the determination of the CKM matrix element |V_us| using inclusive strange hadronic \tau{} decay data. We also review the results for |V_us| extracted from experimental measurements of some…
This paper summarizes the status of selected rare decay experiments in kaon and muon physics.
The most recent progress and future prospects in kaon physics are reviewed. Main results are the first observation of the rare decays KS->pi0ee and KS->pi0mumu by NA48, new K+->pinunu event observed by E949 and new precision measurements of…
This paper presents the analysis of leptonic and semileptonic kaon decays data done by the FlaviaNet Kaon Working group. Data include all recent results by BNL-E865, KLOE, KTeV, ISTRA+, and NA48. Experimental results are critically reviewed…
An overview of the recent past, present and future of flavour physics studies using kaon decays is presented.
Recent results on the kaon rare decays measured in NA48 experiment at CERN are presented.
