Rare Kaon
نویسنده
چکیده
Recent experiments on rare kaon decays are described, with emphasis on the program at the Brookhaven National Laboratory Alternating Gradient Synchrotron. New limits on the modes KL + pe and Kr, -v ee and a preliminary new measurement of the Kr. + pp branching ratio are presented from AGS Experiment 791. Other modes, including K+ + x+p’+e-, K+ + r+ + nothing, and KL -+ r’e+e-, which have been the focus of other AGS experiments, are also discussed. -259@J. Ritchie 1991

متن کاملRadiative Rare Kaon Decays †
We discuss theoretical issues in radiative rare kaon decays. The interest is twofold: to extract useful short-distance information and understand the underlying dynamics. We emphasize channels where either we can understand non-perturbative aspects of QCD or there is a chance to test the Standard Model.
متن کاملNa48: Results on Rare Decays and Future Prospects
Recent results obtained by the NA48 Collaboration on rare neutral kaon and hyperon decays are presented. These include measurements performed with the simultaneous KL and KS beams during the " 0 =" programme as well as investigations of rare KS and neutral hyperon decays using high intensity proton beams at the KS target station. Future projects aiming to search for very rare KS decays and to s...
متن کاملFlavor Physics in Kaon Decays
Kaon physics has a glorious history. Parity violation, CP violation, GIM mechanism, CKM mechanism, Determination of Standard Model (SM) parameters, Hadronic physics all have imprints of kaon physics. Kaon physics still plays an important role in particle physics. Some of the main interests today in kaon physics are: The studies of CP violation and rare decays; Determination of SM parameters; Lo...
متن کاملRare Kaon Decays
We review some recent theoretical results on rare kaon decays. Particular attention is devoted to establish the short distance (direct CP violating) contribution to KL → πee. This is achieved by a careful study of the long distance part. As byproduct, we discuss interesting chiral tests.
متن کاملTheory of Rare Kaon Decays
We review some recent theoretical results on rare kaon decays. Particular attention is devoted to find Standard Model tests. This is theoretically easy in K → πνν, while a careful study of the long distance contributions is needed for KL → πee, KL → μμ and K → ππγ .
