Observation of several sources of violation in decays
LHCb collaboration, R. Aaij, M. Abdelfatah +1116
An amplitude analysis of decays is presented in which six -violating phenomena are judged to be of significance for the first time. This analysis is b…
Measurement of the Liquid Argon Scintillation Pulse Shape Using Differentiable Simulation in the Coherent CAPTAIN-Mills Experiment
A. A. Aguilar-Arevalo, S. Biedron, J. Boissevain +42
The Coherent CAPTAIN-Mills (CCM) experiment is a liquid argon (LAr) light collection detector searching for MeV-scale neutrino and Beyond Standard Model physics signatures. Two hun…
First Event-by-Event Identification of Cherenkov Radiation from Sub-MeV Particles in Liquid Argon
A. A. Aguilar-Arevalo, S. Biedron, J. Boissevain +42
This Letter reports the event-by-event observation of Cherenkov light from sub-MeV electrons in a high scintillation light-yield liquid argon (LAr) detector by the Coherent CAPTAIN…
Testing Meson Portal Dark Sector Solutions to the MiniBooNE Anomaly at CCM
A. A. Aguilar-Arevalo, S. Biedron, J. Boissevain +42
A solution to the MiniBooNE excess invoking rare three-body decays of the charged pions and kaons to new states in the MeV mass scale was recently proposed as a dark-sector explana…
Measurement of the response function of the PIENU calorimeter
A. Aguilar-Arevalo, M. Aoki, M. Blecher +17
Measurements of the response function of the PIENU NaI(T) and CsI crystal calorimeter using a monochromatic 70 MeV/c positron beam at various incidence angles are described.…
Skipper-CCD Sensors for the Oscura Experiment: Requirements and Preliminary Tests
Brenda A. Cervantes-Vergara, Santiago Perez, Juan Estrada +52
Oscura is a proposed multi-kg skipper-CCD experiment designed for a dark matter (DM) direct detection search that will reach unprecedented sensitivity to sub-GeV DM-electron intera…
