Analysis of P _cs(4338) and related pentaquark molecular states via QCD sum rules*

Abstract In this study, we tentatively identify as the \bar{D}\Xi_c molecular state and distinguish isospins of current operators to explore in detail , \bar{D}\Lambda_c \bar{D}_s\Xi_c \bar{D}_s\Lambda_c \bar{D}^*\Xi_c \bar{D}^*\Lambda_c \bar{D}^*_s\Xi_c \bar{D}^*_s\Lambda_c states without strange, with double strange framework QCD sum rules. The present exploration favors identifying ( P_{cs}(4459) ) spin-parity J^P={\dfrac{1}{2}}^- {\dfrac{3}{2}}^- isospin (I,I_3)=(0,0) observation their cousins (I,I_3)=(1,0) J/\psi\Sigma^0/\eta_c\Sigma^0 invariant mass distributions would decipher inner structures.
