[en] Experiment E787 is searching for the rare decay K → πνν at the Brookhaven Alternating Gradient Synchrotron (AGS). To suppress the background from the dominant K → ππ^o branch, a fast lead scintillator sandwich veto assembly system was used. An inefficiency level of ∼ 1 x 10^-6 has been achieved for detecting π^o. The limitations are in part geometrical in part due to photonuclear interactions. Our present understanding of these limitations will be presented together with our upgrading plans using pure CSI crystals. (author). 7 refs., 4 figs

[en] The basic aim of the KAON project is to accelerate 100 μA beams of protons to 30 GeV, an increase of two orders of magnitude over intensities presently available in this energy domain. To achieve this objective a complex of two synchrotrons and three storage rings will be added to the TRIUMF cyclotron

[en] These lectures present the status of the Tokai to Kamioka Experiment (T2K) which just started taking data in early 2010. The goals and methodology for the experiment are presented as well as the challenges and prospects for determining the neutrino mixing parameters leading to neutrino oscillation with a particular attention to the determination of the mixing angle θ₁₃.

[en] The TRIUMF Weak Interaction Symmetry Test (TWIST) experiment aims at a precision measurement of the energy spectrum and of the angular distribution of the decay positrons from highly polarized muons. The experiment has been designed to reach a precision of a few parts in 10^-4 for the so-called Michel parameters which are used to parametrize these distributions. After an engineering run in the fall of 2001, the current data taking phase should provide intermediate results for the ρ and δ parameters at the 10^-3 level by the end of 2003 which will be used to place largely model independent constraints on new physics beyond the Standard Model. A review of the status of the experiment is presented

[en] This paper describes a proposed experiment to detect high energy photons from radiative muon capture on helium-3 using a large acceptance pair spectrometer. The target will consist of 2 liters of liquid helium-3. The negative muons from TRIUMF channel M9 will be stopped in the target. The few muons that undergo radiative capture will produce a photon spectrum which is the sum of the individual spectra from the reactions

[en] A review of the models for radiative and leptonic decay of neutral pions is presented. In particular the form factor slope is extracted from each model and compared with the limiting values of the form factor slope determined by experiment

[en] A particle separator utilizing a magnetic field crossed with an rf electric field has been built and incorporated into the M9 secondary channel to produce a clean negative muon beam at 77 MeV/c +- 5 %. The separator is driven at the main cyclotron frequency (23 MHz) and is phase locked to the primary proton beam. Separation is achieved by using the temporal and velocity differences between the muons produced near the production target (cloud muons), and the pion and electron contaminants in the beam

[en] The positron spectrum from π sup(+) → e sup(+)ν sub(e) decay has been examined for evidence of peaks arising from an admixture in the ν sub(e) weak eigenstate of massive neutrinos. Limits on the intensity of such peaks, together with the measured π → eν branching ratio, have been used to derive constraints on the neutrino mixing parameters over the range 4 MeV < m(ν) < 120 MeV

[en] A measurement of the π→eν branching ratio using a NaI(Tl) spectrometer yields a value GAMMA((π→eν)+(π→eνγ))/ GAMMA((π→μν)+(π→μνγ)) = (1. 218 +- 0.014) x 10^-4. The result is consistent with expectations of the standard electroweak theory incorporating electron-muon universality

[en] This summary covers the physics topics that could benefit from the unprecedented flux of muons produced at the front end of the future neutrino factory. A selection of such opportunities was presented at NuFact02 and their demands on beam properties were evaluated. This summary will survey the rare muon decay experiments and the high precision measurements that could benefit from higher fluxes as well as some of the new programmes that could use very large μ^- fluxes. A number of technological developments relevant to the neutrino factories were also discussed
