# How large is the diffractive contribution to inclusive dijet photoproduction in ultraperipheral collisions at the LHC?

@article{Guzey2020HowLI, title={How large is the diffractive contribution to inclusive dijet photoproduction in ultraperipheral collisions at the LHC?}, author={Vadim Guzey and Michael Klasen}, journal={Physical Review D}, year={2020} }

Using next-to-leading order (NLO) perturbative QCD, we calculate the diffractive contribution to inclusive dijet photoproduction in Pb-Pb ultraperipheral collisions (UPCs) at the LHC and find that it does not exceed 5% in small-$x_A$ bins in the ATLAS kinematics at $\sqrt{s_{NN}}=5.02$ TeV. Its smallness is a result of the restricted kinematics ($p_{T1} > 20$ GeV and $x_A > 0.001$) and the large nuclear suppression of nuclear diffractive parton distribution functions predicted in the leading…
