Prediction of five-flavored pentaquarks

We analyze the possibility of the existence of a fully exotic pentaquark state $udsc\bar{b}$, which is made from the five different flavors participarting in the strong interactions. We investigate the coupled channel effects of the $B^{(\ast )}{\mathrm{\Xi }}_c-B^{(\ast )}{\mathrm{\Xi }}_c^{\mathrm{\prime }}$ system through $t$-channel vector meson exchange to search for such states. A $B{\mathrm{\Xi }}_c$ and a $B \Xi_c^\prime$boundstatearefoundtohavebindingenergiesofabout$10-30$MeVwith$B_s\Lambda_c$and$B_c\Lambda$ being the possible decay channels. Similarly, a bound state is formed in the $B^{\ast }{\mathrm{\Xi }}_c$ and $B^* \Xi_c^\prime$ channels, respectively. These states could be searched for through the $pp\to B_c\mathrm{\Lambda }X$ or $pp\to B_s^{(\ast )}{\mathrm{\Lambda }}_{c}X$ processes by the LHCb collaboration.
