Results from neutrino mass and oscillation experiments now set the mass of the muon neutrino to less than 2 eV/c$^{2}$. This fact, together with our former measurement of the muon momentum in pion decay at rest, pμ+=(29.79200±0.00011) MeV/c, allows

High-intensity secondary beams play a vital role in today's particle physics and materials science research and require suitable detection techniques to adjust beam characteristics to optimally match experimental conditions. To this end we have devel

A positron timing counter (TC) with 30–40 ps time resolution for 50 MeV/c positrons required by the MEG II experiment has been developed. We employed a highly segmented design with 512 scintillator plates (120 × 40 × 5 mm3 and 120 × 50 × 5 mm3)

A new and high-performance generation of detectors based on scintillating fibres coupled to silicon photomultiplier (SiPM, MPPC) is under development. We focus here on the use of this technology as a beam monitoring detector with the following charac

The MEG experiment has set the latest limit of 5.7 × 10 − 13 (90 % C.L.) on the branching ratio of the charged lepton flavor violating decay μ + → e + γ , making use of the most intense continuous surface muon beam in the world at the Paul Sch

The neutron time-of-flight spectrum from the reaction π−p → π0 + n was measured in order to study the acceleration mechanisms in the atomic cascade of pionic hydrogen. For the first time, discrete "high-energy"components up to about 200 eV were

We have measured the Doppler broadening of neutron time-of-flight spectra from the reaction π− p → π0 + n in atomic states. From the data, we infer that the kinetic energy distribution of π− p-atoms in liquid and gaseous hydrogen contains di

We have searched for an admixture of a heavy neutrino state νx in the decay π+→μ++νμ by analyzing the momentum spectrum of a surface muon beam in a magnetic spectrometer. No indications for such a neutrino state were found. In the mass range 0

The CP-violation parameter \etazero\ is determined through the eigentime-dependent asymmetry in the rates of initially tagged \kzerob\ and \kzero\ decaying to \pizero \pizero. From the analysis of the complete data set we obtain the values $ \absetaz
