Understanding spin parity of $P_c(4450)$ and $Y(4274)$ in a hadronic molecular state picture

11 Apr 2017 He Jun

The hidden-charmed pentaquark $P_c(4450)$ and the charmonium-like state $Y(4274)$ are investigated as a $\bar{D}^*\Sigma_c$ and a $D_s\bar{D}_{s0}(2317)$ molecular state, respectively. The spin parities of these two states cannot be well understood if only S-wave $\bar{D}^*\Sigma_c$ and $D_s\bar{D}_{s0}(2317)$ interactions are considered... (read more)
