Hadron photoproduction experiments in LEPS2

N. Muramatsu, A. O. Tokiyasu, T. A. Hashimoto

In the LEPS2 facility constructed at SPring-8, hadron photoproduction experiments have been carried out by using a photon beam with high linear polarization in the tagged energy ra…

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…

Hyperon-Nucleon Spectrometer

Xiaozhi Bai, Xu Cao, Zhe Cao +237

Chirality lies at the heart of low-energy QCD, governing the symmetry structure that shapes hadron masses and strong interaction dynamics. Among the most compelling open questions…

Comprehensive measurement of $η^{'}$ photoproduction off the proton at $E_{γ} < 2.4$ $GeV$

N. Muramatsu, J. K. Ahn, W. C. Chang +61

For the spectroscopy of nucleon resonances at the total energies from the $η^{'}$ -meson production threshold to $2.32$ $GeV$ , photon beam asymmetries of the reaction $γ…

First observation of the $γ$ -ray beam production by the backward Compton scattering of reflected synchrotron radiation in the extreme ultraviolet range

Norihito Muramatsu, Manabu Miyabe, Masahiro Okabe +8

Compton scattering of photons off high-energy electrons is a fundamental quantum mechanical process widely utilized to produce a $γ$ -ray beam for scientific research. Instead of in…
