The in-medium mass of the $\eta^{\prime}$ meson is discussed in a context of partial restoration of chiral symmetry in nuclear medium. The $\eta^{\prime}$ mass is expected to be reduced by order of 100 MeV at the saturation density. The reduction is a consequence of the suppression of the anomaly effect on the $\eta^{\prime}$ mass induced by partial restoration of chiral symmetry. This strong attraction in $\eta^{\prime}$ nuclear systems does not accompany large absorption of $\eta^{\prime… 38 Citations ## Figures from this paper Structure of$\eta^{\prime}$mesonic nuclei in a relativistic mean field theory • Physics Progress of Theoretical and Experimental Physics • 2019 The structure and the energy spectrum of the$\eta^{\prime}$mesonic nuclei are investigated in a relativistic mean field theory.
