Book excerpt: Experiment E865 at the BNL AGS is a search for the lepton number violating decay K → ?+?+e− with an expected sensitivity of 3 × 10−12. The experimental apparatus involves a magnetic spectrometer with two Cerenkov counters, a calorimeter and a muon detector for particle identification. In addition, other rare K+ decays are studied. The experiment has been collecting data since 1995, and preliminary results are presented.

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.

Book excerpt: I review the status and future prospects of searches for forbidden and highly kaon suppressed decays. This workshop comes as we are poised at the threshold of a new generation of rare K decay experiments. There are new experiments running or about to run at KEK, BNL, FNAL, and CERN. In another year or so these will be joined by the KLOE experiment at DA[Phi]NE. The good news is that it's a very exciting time. The bad news, at least for a reviewer, is that there aren't too many new results. Thus I'll be giving a little more attention than usual to what the experimenters expect to do. My discussion of rare K decays covers processes that are forbidden in the Standard Model, those that highly suppressed and to a smaller extent, those that are merely discouraged.

Book excerpt: There have been a proposal (accepted - E777) and a letter-of-intent to search for K .-->. .pi.mu.+e− to a branching ratio better than 10−11. This motivation is to test different types of lepton number conservation - specifically, there is a boson in technicolor models which would allow such decays at a level around 10−1°. This note discusses the E777 experiment, reasons for doing the experiment at the AGS, and the prospects for looking for even smaller branching ratios. A level of B.R. 4.8 x 10−9 (90% C.L.) for K+ .--. .pi.+.mu.+e− was achieved in a CERN experiment designed to study Ke4 decay. That experiment used a separated 8 x 104/pulse K+ beam with a PWC/spark chamber detector and no muon identification. E777 will use an unseparated beam with 2 x 107K/sup +//pulse, PWCs, and muon identification. Cherenkovs will be designed to not misidentify particles, at a reduced efficiency. For example, two counters will be filled with H2 gas at atmospheric pressure to identify electrons. This reduces delta-ray contamination, at a cost of reduced efficiency for identifying the electrons. They chose a K/sup +/ momentum of 6 Gev/c (and, thus, to do the experiment at the AGS) for good particle identification.

Book excerpt: AGS-787, BNL-Princeton-TRIUMF, began taking data in February 1988 on rare K decays into .pi. and non-interacting neutrals. Recent observations of B-/bar B/ mixing have sharpened the branching ratio prediction of the three generation standard model, (SM), to (approximately) 1-5 x 10−1° for .pi.+.nu./bar /nu//. The detector has 2.pi. acceptance for this decay and 4.pi. acceptance for background gammas. A very large window for viewing new physics exists between the SM value and the previous experimental limit of 1.4 x 10−7. Several other predicted rare K+ decays can be detected. The performance of the detector is described. 8 refs., 4 figs.

Book excerpt: The past few years have seen an evolution in the study of rare K decays from a concentration on explicitly Standard Model (SM) violating decays such as K{sub L}° → [mu]e, to one on SM-allowed but suppressed decays such as K → [pi][nu]{bar {nu}}, in which short-distance interactions are dominant. There are also a number of recent experimental and theoretical studies of long-distance-dominated decays, but they do not have space to cover these, with the exception of those that are needed in the discussion of the short-distance-dominated processes.
