Abstract
The inclusive production of pseudoscalar heavy quarkoniua ($\eta_c,\, \eta_b,\, B_c$), double heavy baryon $\Xi_{QQ^\prime}$ ($Q^{(\prime)}=c,\,b$ quarks) and tetraquark $T_{QQ}$ in heavy ion ultraperipheral collisions (UPCs) are studied. Numerical results indicate that the experimental investigation for $\eta_c,\, \Xi_{cc}$, and $T_{cc}$ are feasible at the coming HL-LHC and future FCC. The heavy ion UPCs open another door of the study on the production of these doubly heavy hadrons.
