| Description: |
We compute the inclusive production cross section in ultraperipheral Pb-Pb collisions at the LHC as a function of the transverse momentum and rapidity. These calculations are carried out within the new generalized photon-nucleus FONLL ( ) framework, which can predict photonuclear cross sections for charm and beauty hadrons in electron-proton, electron-nucleus, and ultraperipheral heavy-ion collisions. The framework relies on fixed-order next-to-leading logarithm (FONLL) to model heavy-quark production in photonuclear collisions and employs a photon-flux reweighting procedure to describe the production cross sections in ultraperipheral heavy-ion collisions. The calculations are first validated against the photoproduction cross sections of in electron-proton collisions at HERA. The predictions for the production cross section in ultraperipheral Pb-Pb collisions at the LHC are then presented and compared to the first experimental results obtained by CMS at . The predictions are benchmarked against different choices of nuclear parton distribution functions, fragmentation functions, and renormalization and factorization scales. |
