Demonstration of a cryogenic, switchable electron source for low-temperature detector calibration

D. A. Bennett, M. Borghesi, P. Campana +17

We present the realization of a prototype of a compact, switchable electron source operating at cryogenic temperatures, demonstrated at energies ranging from 100 eV to 300 eV, and…

Letter Of Intent for a future experiment at the High Intensity Muon Beam facility at PSI

Paolo Walter Cattaneo, Wataru Ootani, Francesco Renga +61

Searches for charged lepton flavor violation in the muon sector stand out among the most sensitive and clean probes for physics beyond the Standard Model. Currently, $μ^+ \to \mat…

Impact of embedded Ho on the performance of the transition-edge sensor microcalorimeters of the HOLMES experiment

Douglas Bennett, Matteo Borghesi, Pietro Campana +19

We present a detailed investigation of the performance of transition-edge sensor (TES) microcalorimeters with Ho atoms embedded by ion implantation, as part of the HOLMES e…

New limit on the μ+->e+γdecay with the MEG II experiment

K. Afanaciev, A. M. Baldini, S. Ban +65

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…

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…
