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…

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…
