Book excerpt: In recent years the study of the rare decays of kaons has had three primary motivations. The first is the search for physics beyond the Standard Model (BSM). Virtually all attempts to redress the theoretical shortcomings of the Standard Model (SM) predict some degree of lepton flavor violation (LFV). Decays such as K{sub L} → [mu]{sup {+-}}e{sup {-+}} have very good experimental signatures and can consequently be pursued to remarkable sensitivities. These sensitivities correspond to extremely high energy scales in models where the only subpression is that of the mass of the exchanged field. There are also theories that predict new particles created in kaon decay or the violation of symmetries other than lepton flavor. The second is the potential of decays that are allowed but that are extremely suppressed in the SM. In several of these, the leading component is a G.I.M.-suppressed [1] one-loop process that is quite sensitive to fundamental SM parameters such as V{sub td}. These decays are also potentially very sensitive to BSM physics. Finally there are a number of long-distance-dominated decays which can test theoretical techniques such as chiral Lagrangians that purport to explain the low-energy behavior of QCD. Knowledge of some of these decays is also needed to extract more fundamental information from certain of the one-loop processes. This field is quite active as indicated by Table 1 that lists the decays for which results have been forthcoming in the last couple of years as well as those that are under analysis. Thus in a short review such as this, one must be quite selective. Recent results on rare kaon decays are reviewed and prospects for future experiments are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Small effects that are beyond the current standard models of physics are often signatures for new physics, revealing fields and mass scales far removed from contemporary experimental capabilities. This perspective motivates sensitive searches for rare decays of the kaon. The current status of these searches is reviewed, new results are presented, and progress in the near future is discussed. Opportunities for exciting physics research at a hadron facility are noted. 5 refs., 8 figs., 1 tab.

This book was released on 2021-07-14 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to Lev Okun, who passed away in November 2015. He was a true pioneer in probing fundamental dynamics.The book has two objectives. First is to showcase Okun's impact for decades since 1963, when he published his remarkable book Weak Interaction of Elementary Particles. Second is to present the current progress of our scientific community in the studies of our Universe. New directions and possible future developments are discussed, often using the past as a guide. The authors mostly focus on CP asymmetries in the transitions of hadrons and leptons, but they also discuss their rare decays, and talk about axions and supersymmetry, and possible connections with dark matter, extra dimensions, baryogenesis and multiverse.This book is suitable for readers who know quantum mechanics and quantum field theories in general.

Available in PDF, EPUB and Kindle. Book excerpt: "Physics at KAON", an international meeting jointly organized by the KFA Jillich and TRI UMF, was held in the Physikzentrum Bad Honnef from June 7 through June 9, 1989. This was one of a series of meetings - the first one in Europe - in which plans for the medium energy physics laboratory KAON were presented and some aspects of the physics at this new facility were discussed. The meeting focussed mainly on the topics of hadron spectroscopy, J{ -meson scattering, strangeness in nuclei, and rare decays. Also presented were some of the research programs at SATURNE and COSY which may well lead to KAON physics in the future. These proceed ings include articles which summarize our current experimental and theoretical knowledge in the various areas, as well as papers which describe lines of research feasible with KAON. The large number of participants - limited, in fact, by the capacity of the Physikzentrum - clearly demonstrates the great interest of the European physics community in the research avenues which will be opened by the high-intensity hadron facilities.

Available in PDF, EPUB and Kindle. Book excerpt: The E391a collaboration searched for rare kaon decays at the KEK 12 GeV proton synchrotron in Tsukuba, Japan. This thesis focuses on using a blind analysis to search for the rare decay K0L→p0p 0nn.&d1; In a blind analysis, the signal region is kept hidden while choosing event selection criteria. The background was estimated through the bifurcation method to be 0.26 +/- 0.18stat +/- 0.01 syst. The kaon flux is estimated to be (5.61 +/- 0.16 stat +/- 0.26syst) x 109. After opening the box, we observed zero event. Therefore, we set an upper limit of the branching ratio of the K0L→p0p 0nn&d1; decay at 1.1 x 10-6 at the 90% confidence level.

This book was released on 2009 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A search for K0L & rarr; pi0nunu was performed on data taken during the last Run of the E391a experiment at KEK. Blind analysis approach was adopted. The acceptance for the signal was improved from previous analysis by about 40% because of a better understanding of the background. With (3.48 +/- 0.25) * 109 K0L decays, we found no candidate events. An upper limit of 6.96 x 10-8 on the K0L & rarr; pi0nunu branching ratio was set at the 90% confidence level.

Download or read book SEARCH FOR THE RARE KAON DECAY K →?+?{bar {nu}} written by and published by . This book was released on 2003 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the search for the rare decay K →?+?{bar {nu}} in the pion momentum region 140 MeV/c ≤ P{sub {pi}+} ≤ 195 MeV/c. This is a Flavor Changing Neutral Current (FCNC) decay which is forbidden to the first order in the Standard Model (SM) by the GIM mechanism. However, this decay mode is allowed in the second order by two Z-Penguin and one box diagram and is expected to have a branching ratio of (0.72 ± 0.21) x 10−1°. This decay mode is sensitive to the coupling of top to down quark and therefore a measurement of the branching ratio for this decay mode provides a measurement of the Cabibbo-Kobayashi-Maskawa matrix element V{sub td}. The recent observation of two events in the pion momentum region 211 MeV/c ≤ P{sup {pi}+} ≤ 229 MeV/c estimates a branching ratio of 1.57{sub -0.82}{sup +1.75} x 10−1° for the same decay mode. We have extended the search for this decay to the lower pion momentum region. Data collected by the Experiment E787 at Brookhaven National Laboratory during the 1996 and 1997 run were analyzed in this thesis.
