论文摘要
我们在Ultraperipheral（UPCS）$ aa $ collisions中讨论了相关的$ c \ bar {c} $和$ b \ bar {c} $ {c} $ {c} $ {c} $ {c} $ {c} $ {c} $ {c} $ {c} $ {c} $。我们得出了包容性DPS袖珍配方的类似物和光子能量依赖的有效横截面，考虑到硬sps散射之间的重叠。我们为$ c \ bar {c} b \ bar {b} $生产过程提供了DPS横截面的数值预测，该过程是在LHC和FCC校园的典型能量下的典型能量，并且还表征了总UPC DPS Cross Cross Cross crots Cross crots Cross Cross crots cross cross $ a $ a $ a $ a的依赖性。
We discuss the associated $c\bar{c}$ and $b\bar{b}$ quark pairs production in the double-parton scattering (DPS) process in ultraperipheral (UPCs) $AA$ collisions. We derive an analogue of the inclusive DPS pocket formula and the photon-energy dependent effective cross section considering an overlap between the hard SPS scatterings. We provide numerical predictions for the DPS cross sections for the $c\bar{c}b\bar{b}$ production process at the typical energies of $AA$ UPCs at the LHC and FCC colliders and also characterize the $A$ dependence of the total UPC DPS cross section.
