Does the KARMEN time anomaly originate from a beam-correlated background?
F. Atchison, M. Daum, P. -R. Kettle +1
The time anomaly of neutrino events observed in the KARMEN detector at the ISIS facility is discussed. We show that beam-correlated neutron events are not completely suppressed by…
Target Studies for Surface Muon Production
F. Berg, L. Desorgher, A. Fuchs +8
Meson factories are powerful drivers of diverse physics programmes. With beam powers already in the MW-regime attention has to be turned to target and beam line design to further s…
Research Proposal for an Experiment to Search for the Decay μ -> eee
A. Blondel, A. Bravar, M. Pohl +22
We propose an experiment (Mu3e) to search for the lepton flavour violating decay mu+ -> e+e-e+. We aim for an ultimate sensitivity of one in 10^16 mu-decays, four orders of magnitu…
Technical design of the phase I Mu3e experiment
K. Arndt, H. Augustin, P. Baesso +102
The Mu3e experiment aims to find or exclude the lepton flavour violating decay at branching fractions above . A first phase of the experiment using an…
Measurement of the radiative decay of polarized muons in the MEG experiment
MEG Collaboration, A. M. Baldini, Y. Bao +68
We studied the radiative muon decay by using for the first time an almost fully polarized muon source. We identified a large sample (~13000) of these decay…
Operation and performance of MEG II detector
MEG II Collaboration, K. Afanaciev, A. M. Baldini +82
The MEG II experiment, located at the Paul Scherrer Institut (PSI) in Switzerland, is the successor to the MEG experiment, which completed data taking in 2013. MEG II started fully…

The MEG II experiment, based at the Paul Scherrer Institut in Switzerland, reports the result of a search for the decay from data taken in the first physics run in…
New constraint on the existence of the mu+-> e+ gamma decay
MEG Collaboration, J. Adam, X. Bai +71
The analysis of a combined data set, totaling 3.6 \times 10^14 stopped muons on target, in the search for the lepton flavour violating decay mu^+ -> e^+ gamma is presented. The dat…

This letter reports the result of the search for the decay μ+->e+γundertaken at the Paul Scherrer Institut in Switzerland with the MEG II experiment using the data collected in t…
A non-invasive ultra-thin luminophore foil detector system for secondary beam monitoring
F. Berg, D. N. Grigoriev, Z. Hodge +5
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…
New limit on the lepton-flavour violating decay mu -> e gamma

We present a new result based on an analysis of the data collected by the MEG detector at the Paul Scherrer Institut in 2009 and 2010, in search of the lepton flavour violating dec…
A limit for the mu -> e gamma decay from the MEG experiment
MEG collaboration, J. Adam, X. Bai +67
A search for the decay mu -> e gamma, performed at PSI and based on data from the initial three months of operation of the MEG experiment, yields an upper limit on the branching ra…
The design of the MEG II experiment
A. M. Baldini, E. Baracchini, C. Bemporad +72
The MEG experiment, designed to search for the mu+->e+ gamma decay at a 10^-13 sensitivity level, completed data taking in 2013. In order to increase the sensitivity reach of the e…

J. Adam, X. Bai, A. M. Baldini +73
The MEG (Mu to Electron Gamma) experiment has been running at the Paul Scherrer Institut (PSI), Switzerland since 2008 to search for the decay \meg\ by using one of the most intens…
Search for the X17 particle in processes with the MEG II detector
The MEG II collaboration, K. Afanaciev, A. M. Baldini +64
The observation of a resonance structure in the opening angle of the electron-positron pairs in the Li(p,\ee) Be reaction was claimed and interpreted as the production…
