The new $P_{\mathrm{cs}}(4459)$, $Z_{\mathrm{cs}}(3985)$, $Z_{\mathrm{cs}}(4000)$ and $Z_{\mathrm{cs}}(4220)$ and the possible emergence of flavor pentaquark octets and tetraquark nonets

Abstract

Our hadro-charmonium and compact tetraquark model predictions, published before the BESIII and LHCb experimental data for the $Z_{\mathrm{cs}}(3985)$ and $Z_{\mathrm{cs}}(4003)$ tetraquarks were released, match surprisingly well with them. Here, we extend our results for the $P_{\mathrm{cs}}$ states to $\Lambda$ + charmonium configurations and also our hadro-charmonium predictions for $Z_{\mathrm{c}}$ and $X_{\mathrm{c}}$ tetraquarks to charmonium + pion/eta. We use them, in combination with our previous findings, to discuss the possible emergence of SU(3)${}_{\mathrm{f}}$ pentaquark octets and tetraquark nonets in the hidden-charm sector as a tool to discriminate among different theoretical interpretations.
