Accidental Peccei-Quinn symmetry from gauged U(1) and a high quality axion

K. S. Babu, B. Dutta, Rabindra N. Mohapatra

A bstract We construct explicit models that solve the axion quality problem originating from quantum gravitational effects. The general strategy we employ is to supplement the Standard Model and its grand unified extensions by an anomaly-free axial U(1) a symmetry that is …

Monophotons from scalar portal dark matter at neutrino experiments

B. Dutta, Debopam Goswami, Aparajitha Karthikeyan

A bstract In this work, we investigate monophoton signatures arising from dark matter via a 2 → 3 scattering process χ + N → χ + N + γ that is mediated by a virtual scalar and a Standard Model photon. Since …

Measurement of the liquid argon scintillation pulse shape using differentiable simulation in the coherent CAPTAIN-Mills experiment

A. A. Aguilar-Arevalo, Sandra Biedron, J. Boissevain, M. Borrego et autres

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 hundred eight-inch photomultiplier tubes instrument the seven-ton fiducial volume with 50% photocathode coverage to detect light produced by …

Measurement of the Liquid Argon Scintillation Pulse Shape Using Differentiable Simulation in the Coherent CAPTAIN-Mills Experiment

A. A. Aguilar-Arevalo, Sandra Biedron, J. Boissevain, M. Borrego et autres

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 hundred 8-inch photomultiplier tubes (PMTs) instrument the 7 ton fiducial volume with 50% photocathode coverage to detect light …

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC

DUNE Collaboration, A. Abed Abud, B. Abi, R. Acciarri et autres

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6x6x6m3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of …
