Direct measurement of the in-medium $η^{'}$ mass spectrum through the $γ γ$ decay channel

Y. Matsumura, N. Muramatsu, T. A. Hashimoto +58

We measured the invariant mass of the $η^{'} (958)$ meson through the $η^{'} \to γ γ$ decay channel to search for possible character change of $η^{'}$ in a nuclear mediu…

Incommensurate Magnetic Ordered Phase with Enhanced Low-Temperature Magnetic Specific Heat in SmAu $_{3}$ Al $_{7}$

Ryuji Higashinaka, Takuma Iwami, Kohsuke Saitou +12

Neutron scattering and muon spin rotation ( $μ$ SR) measurements on single-crystal SmAu $_{3}$ Al $_{7}$ reveal magnetically ordered states associated with successive transitions at $T_{\rm…

Magnetic Order of Dresselhaus-type Antiferromagnet EuIr $_{4}$ In $_{2}$ Ge $_{4}$ Studied by Single Crystal Neutron Diffraction

Chihiro Tabata, Koji Kaneko, Akiko Nakao +3

The magnetic order of EuIr $_{4}$ In $_{2}$ Ge $_{4}$ , which crystallizes in a Dresselhaus-type noncentrosymmetric tetragonal structure, was investigated using two complementary single-crysta…

The Search for $K_{L} \to π^{0} π^{0} γ γ$ and $K_{L} \to π^{0} π^{0} X$ where $X \to 2 γ$ at the KOTO Experiment

J. Redeker, C. Lin, Y. W. Wah +23

We performed searches for $K_{L} \to π^{0} π^{0} X$ where $X$ may be an axion-like particle which promptly decays to two photons, and the first search for $K_{L} \to π^{0} π^{0} γ γ$ …

Quadrupole transitions of $^{10}$ C and their isospin symmetry with $^{10}$ Be

Takayuki Myo, Mengjiao Lyu, Qing Zhao +6

We investigate the structures of $^{10}$ C focusing on the quadrupole properties in comparison with the mirror nucleus $^{10}$ Be. We describe $^{10}$ C and $^{10}$ Be in the variation…

Kitaev interactions in the van der Waals antiferromagnet VBr3

Zeyu Kao, Yimeng Gu, Yiqing Gu +5

Van der Waals materials hosting Kitaev interactions are promising platforms for exploring exotic quantum phenomena. Here, we report inelastic neutron scattering investigations of t…
