| contents | We study the double heavy baryon $Ξ_{QQ'}$ and tetraquark $T_{QQ}$ production through photon-photon and photon-gluon fusion via ultraperipheral collisions at the LHC and FCC within the framework of nonrelativistic QCD factorization formalism. Various ion-ion collisions are taken into account, two cc(bb)-diquark configurations ($[cc(bb),{^3S_1}\mbox{-}\bar{\bm{3}}]$ and $[cc(bb),{^1S_0}\mbox{-}\bm{6}]$) and four bc-diquark configurations ($[bc,{^3S_1}\mbox{-}\bar{\bm{3}}]$, $[bc,{^3S_1}\mbox{-}\bm{6}]$, $[bc,{^1S_0}\mbox{-}\bar{\bm{3}}]$ and $[bc,{^1S_0}\mbox{-}\bm{6}]$) are considered in the calculation. Numerical results indicate that the $[cc,{^3S_1}\mbox{-}\bar{\bm{3}}]$ diquark provides dominant contribution for $Ξ_{cc}$ ($T_{cc}$) production, and a considerable number of $Ξ_{cc}$ ($T_{cc}$) can be produced. Due to the event topologies for ultraperipheral collision are very clear, the background from various QCD interactions can be suppressed, hence the experimental investigation for $Ξ_{cc}$ and $T_{cc}$ are feasible. The productions for $Ξ_{bc/bb}$ are also discussed, leaving only slightly possibility for $Ξ_{bc}$ through photon-gluon fusion with ultraperipheral collisions at the FCC. |
