Short-Range Tests of the Gravitational Inverse-Square Law
Jiro Murata, Takuhiro Fujiie, Sae Suzuki
Experimental constraints on the gravitational inverse-square law at short range are presented, employing a consistent formalism across a wide range of length scales. We provide com…
Proof-of-Principle Experiment on a Displacement-Noise-Free Neutron Interferometer for Gravitational Wave Detection
Shoki Iwaguchi, Takuhiro Fujiie, Taro Nambu +13
The displacement-noise-free interferometer (DFI) is designed to eliminate all displacement-induced noise while retaining sensitivity to gravitational wave (GW) signals. Ground-base…
Lifetime measurement of the muonic atoms of enriched Si isotopes
R. Mizuno, M. Niikura, S. Akamatsu +12
Background: A muonic atom, composed of a negative muon and an atomic nucleus, undergoes two primary decay processes: muon-electron decay and muon nuclear capture. The branching rat…
Current-readout technique for ultra-high-rate experiments
Maki Wakata, Shoei Akamatsu, Takuhiro Fujiie +9
This study developed a new current-readout technique capable of handling measurements with high count rates reaching 1 Gcps. By directly capturing the output current of a photomult…
