Toward testing antinucleon$\unicode{x2013}$nucleus optical potentials with antineutron scattering lengths

Hiroyuki Fujioka, Sayaka Ishii

The antineutron$\unicode{x2013}$nucleus scattering length is currently known only indirectly, via antiproton$\unicode{x2013}$nucleus optical potentials fitted to level shifts and w…

Impact of a Reflecting Material on a Search for Neutron--Antineutron Oscillations using Ultracold Neutrons

Hiroyuki Fujioka, Takashi Higuchi

We investigate neutron--antineutron oscillations of ultracold neutrons in a storage bottle represented by a one-dimensional potential. The experimental sensitivity is determined by…

Novel concept for low-energy antineutron production and its application for antineutron scattering experiments

Alessandra Filippi, Hiroyuki Fujioka, Takashi Higuchi +1

Extensive data of antiproton scattering cross sections with protons and nuclei have advanced our understanding of hadronic interactions with antinucleons. However, low-energy antin…

Precision Spectroscopy of Antiprotonic Atoms for Investigation of Low-energy Antinucleon-nucleus Interactions

Takashi Higuchi, Hiroyuki Fujioka

We propose a high-precision x-ray spectroscopy experiment of antiprotonic atoms to advance the understanding of low-energy antinucleon-nucleus interactions. The current leading mod…

Feasibility of the observation of mesic nuclei in the semi-exclusive C() reaction

Natsumi Ikeno, Yuko Higashi, Hiroyuki Fujioka +7

We study theoretically the feasibility of the semi-exclusive C() reaction for the observation of mesic nuclei using the microscopic transport model JAM.…
