Spectral function of the $η^{'}$ meson in nuclear medium based on phenomenological models

Shuntaro Sakai, Daisuke Jido

The in-medium modification of the spectral function of the $η^{'}$ meson with and without the spatial momentum is studied with the $T ρ$ approximation by employing two phenomenological…

Production of $N^{} (1535)$ and $N^{} (1650)$ in $Λ_{c} \to K ˉ^{0} η p$ $(π N)$ decay

R. Pavao, S. Sakai, E. Oset

In order to study the properties of the $N^{*}$ (1535) and $N^{*}$ (1650) we calculate the mass distributions of $M B$ in the $Λ_{c} \to K ˉ^{0} M B$ decay, with $MB=πN(I=1/2),ηp…

Effect of the final state interaction of $η^{'} N$ on the $η^{'}$ photoproduction off nucleon

Shuntaro Sakai, Atsushi Hosaka, Hideko Nagahiro

We investigate the $η^{'}$ photoproduction off the nucleon with a particular interest in the effect of the final-state interaction (FSI) of the $η^{'}$ meson and nucleon $(η^{'} N)$ based on…

Possible relevance of the softening of the sigma meson to $η$ decay into 3 $π$ in the nuclear medium

Shuntaro Sakai, Teiji Kunihiro

We investigate the role of the softening of the scalar-isoscalar (sigma) meson in the $η \to π^{+} π^{-} π^{0}$ and $3 π^{0}$ decay widths in the symmetric nuclear medium using a linear…

The $η^{'} N$ interaction from a chiral effective model and $η^{'}$ - $N$ bound state

Shuntaro Sakai, Daisuke Jido

The $η^{'}$ mass reduction in the nuclear medium is expected from the degeneracy of the pseudoscalar-singlet and octet mesons when chiral symmetry is manifest. In this study, we inves…

The $η$ decay into 3 $π$ in asymmetric nuclear medium

Shuntaro Sakai, Teiji Kunihiro

We explore how the $η$ - $π^{0}$ mixing angle and the $η$ meson decay into $π^{+} π^{-} π^{0}$ and 3 $π^{0}$ are modified in the nuclear medium on the basis of the in-medium chiral effectiv…
