Development and Characterization of Low-Scattering Vanadium Nanoparticle Targets for Short-Range Interaction Searches
Masayuki Hiromoto, Tatsushi Shima, Christopher C. Haddock +8
We developed high-purity vanadium-based nanoparticle targets for neutron scattering experiments aimed at exploring gravity-like short-range new interactions in the submicron regime…
First Constraint on P-odd/T-odd Cross Section in Polarized Neutron Transmission through Transversely Polarized La
Rintaro Nakabe, Clayton J. Auton, Shunsuke Endo +27
We report the first constraint on time-reversal invariance violating (TRIV) effects in polarized neutron transmission through a transversely polarized La target. We formula…
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…
Precision measurements of muonium and muonic helium hyperfine structure at J-PARC
Patrick Strasser, Mitsushi Abe, Kanta Asai +19
At the J-PARC Muon Science Facility (MUSE), the MuSEUM collaboration is now performing new precision measurements of the ground state hyperfine structure (HFS) of both muonium and…
