New Limit on Axion-Like Dark Matter using Cold Neutrons
Ivo Schulthess, Estelle Chanel, Anastasio Fratangelo +8
We report on a search for dark matter axion-like particles (ALPs) using a Ramsey-type apparatus for cold neutrons. A hypothetical ALP-gluon-coupling would manifest in a neutron ele…
Limit on the Fierz Interference Term b from a Measurement of the Beta Asymmetry in Neutron Decay
Heiko Saul, Christoph Roick, Hartmut Abele +7
In the standard model of particle physics, the weak interaction is described by vector and axial-vector couplings only. Non-zero scalar or tensor interactions would imply an additi…
High Precision Experiments with Cold and Ultra-Cold Neutrons
Hartmut Abele, Tobias Jenke, Erwin Jericha +5
This work presents selected results from the first round of the DFG Priority Programme SPP 1491 "precision experiments in particle and astroparticle physics with cold and ultra-col…
Characterization of Aluminum Microwave SQUID Multiplexers for CENS Detection
James Amidei, Antoine Armatol, Corinne Augier +92
We present the design, fabrication, and characterization of an aluminum-based six-channel microwave SQUID multiplexer (MUX) prototype for transition-edge sensor (TES) readout i…
Characterization of mini-CryoCube detectors from the Ricochet experiment commissioning at the Institut Laue-Langevin
Antoine Armatol, Corinne Augier, Louis Bailly-Salins +83
The Ricochet experiment aims to measure the coherent elastic neutrino-nucleus scattering process from antineutrinos emitted by a research nuclear reactor operated by the Institut L…
Measurement of the Weak Axial-Vector Coupling Constant in the Decay of Free Neutrons Using a Pulsed Cold Neutron Beam
Bastian Märkisch, Holger Mest, Heiko Saul +8
We present a precision measurement of the axial-vector coupling constant in the decay of polarized free neutrons. For the first time, a pulsed cold neutron beam was used for…
