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: We present a concise review of the theoretical status of rare K →??{bar?} decays in the standard model (SM). Particular attention is thereby devoted to the recent calculation of the next-to-next-to-leading order (NNLO) corrections to the charm quark contribution of K →?+?{bar {nu}}, which removes the last relevant theoretical uncertainty from the K →?{nu}{bar {nu}} system.

Book excerpt: We have observed 1 event consistent with the signature expected of the rare decay of a positive kaon to a positive pion and a neutrino anti-neutrino pair. In the examined momentum region of 211 to 230 MeV/c in the center of mass of the kaon we estimated the backgrounds to be about 0.08[+-] 0.03 events. From this observation we estimate the branching ratio to be 4.2[sub[minus]3.5][sup+9.7] x 10[sup[minus]10]. In this presentation I will explain the experiment, and the analysis techniques. I will also discuss the expected improvements in the near future from the analysis of new data sets.

Book excerpt: This thesis describes the search for KL 2![pi]0[pi]0[mu]+[mu]-, which was conducted using data collected by the KTeV Experiment at Fermi National Accelerator Laboratory in Batavia, Illinois. Although this decay mode is possible within the Standard Model, it is limited to a very narrow band of phase space. The HyperCP Experiment has recently observed three [Sigma]+ 2!p[mu]+[mu]- events within a narrow dimuon mass range of 213.8 MeV/c2 to 214.8 MeV/c2. This suggests that the process could occur via a neutral intermediary particle, [Sigma]+ 2!pX0 2!p[mu]+[mu]-, with an X0 mass of 214.3 MeV/c2 ± 0.5 MeV/c2 . Since the X0 has a light mass and a low interaction probability, then it is most likely a new neutral boson that exists beyond the Standard Model. Recent theoretical predictions suggest that the decay mode KL 2![pi]0[pi]0[mu]+[mu]- can also occur via the aforementioned neutral boson: KL 2![pi]0[pi]0X02![pi]0[pi]0[mu]+[mu]-. Therefore, in addition to a Standard Model measurement, the search for KL 2![pi]0[pi]0[mu]+[mu]- is also carried out in an effort to address the viability of X0 in explaining the HyperCP phenomena. Measurement of the upper limits presented in this thesis were performed using blind analysis techniques. The upper limit of the decay KL 2![pi]0[pi]0[mu]+[mu]- has been measured in this thesis to be BR(KL 2![pi]0[pi]0[mu]+[mu]- )
