Theoretical study of $f_0(980)$, $a_0(980)$ and $\mathrm{\Xi }(1\mathrm{/}{2}^{-})$ in the process ${\mathrm{\Xi }}_c^{+}\to {\mathrm{\Sigma }}^{+}{K}^{+}{K}^{-}$

We employed the chiral unitarity approach to investigate the decay process ${\mathrm{\Xi }}_c^{+}\to {\mathrm{\Sigma }}^{+}{K}^{+}{K}^{-}$, by considering that the low lying nucleon resonance $\mathrm{\Xi }(1\mathrm{/}{2}^{-})$ and the low lying scalar meson $f_0(980)$ and $a_0(980)$ that could be dynamically generated through $S$-wave pseudoscalar meson-octet baryon and the $S$-wave pseudoscalar meson-pseudoscalar meson interactions, respectively. In the invariant mass distributions of ${\mathrm{\Sigma }}^{+}{K}^{-}$ and $K^{+}{K}^{-}$, we observe a distinct peak structure associated with the resonant state $\mathrm{\Xi }(1\mathrm{/}{2}^{-})$ and a bit enhancement near the $K^{+}{K}^{-}$ threshold that is corresponding to the mesons $f_0(980)$ and $a_0(980)$, respectively. Consequently, we recommend more precise experimental measurements of this process in the future.
