Comprehensive measurement of η ′ photoproduction off the proton at E γ < 2.4 GeV

N. Muramatsu, J. K. Ahn, W. C. Chang, J. Y. Chen et autres

For the spectroscopy of nucleon resonances at the total energies from the $η^\prime$-meson production threshold to $2.32$ $\mathrm{GeV}$, photon beam asymmetries of the reaction $γp \to η^\prime p$ were measured together with total and differential cross sections by analyzing the two decay …

Prospects for Pentaquark Baryon Search with the Upgraded LEPS2 Facility

T. Nakano, S. Ajimura, Y. Asano, S. Daté et autres

We present prospects for the \({\mit \Theta }^+\) pentaquark baryon search using the newly constructed LEPS2 facility at SPring-8. The LEPS2 detector system features significant improvements in acceptance for multi-particle final states compared to previous experiments. Our search employs two complementary strategies: …

We present prospects for the $\Theta^+$ pentaquark baryon search using the newly constructed LEPS2 facility at SPring-8. The LEPS2 detector system features significant improvements in acceptance for multi-particle final states compared to previous experiments. Our search employs two complementary strategies: direct production …

First measurement of differential cross sections and photon beam asymmetries for photoproduction of the f0(980) meson decaying into π0π0 at Eγ<2.4 GeV

N. Muramatsu, S. K. Wang, Q. He, J. K. Ahn et autres

For the first time, differential cross sections and photon beam asymmetries were measured for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}{f}_{0}(980)p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}p$ by using a linearly polarized photon beam up to $2.4\phantom{\rule{4pt}{0ex}}\mathrm{GeV}$ and a liquid hydrogen target. The ${f}_{0}$(980) photoproduction signal was clearly observed owing to the …

Differential cross sections and photon beam asymmetries of η photoproduction on the proton at Eγ=1.3–2.4 GeV

Toshikazu Hashimoto, T. Nam, N. Muramatsu, J. K. Ahn et autres

We report exclusive measurements for the $\ensuremath{\eta}$ photoproduction on a proton target. The differential cross sections and photon beam asymmetries of the $\ensuremath{\gamma}p\ensuremath{\rightarrow}\ensuremath{\eta}p$ reaction are measured in a center-of-mass energy ($W$) range of 1.82--2.32 GeV and a polar angle range of $\ensuremath{-}1.0<cos{\ensuremath{\theta}}_{\mathrm{c}.\mathrm{m}.}^{\ensuremath{\eta}}<0.6$ …

Coherent photoproduction of the neutral-pion and η -meson on the deuteron at incident energies below 1.15 GeV

T. Ishikawa, A. Fix, H. Fujimura, H. Fukasawa et autres

Coherent photoproduction of the neutral-pion and $\ensuremath{\eta}$-meson on the deuteron, $\ensuremath{\gamma}d\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}\ensuremath{\eta}d$, was experimentally studied at incident photon energies ranging from the reaction threshold to 1.15 GeV. The total cross section demonstrates a rapid rise below 1 GeV. The data are underestimated by …
