Predictions of exclusive Υ photoproduction at the LHC and future colliders

The cross section for exclusive Upsilon ultraperipheral photoproduction at present and future colliders is determined using the low x gluon parton distribution function extracted from an analysis of exclusive J/psi measurements performed at the Hadron-Electron Ring Accelerator and the Large Hadron Collider. Predictions are given at next-to-leading order in collinear factorization over a wide gamma p centre-of-mass energy range, calculated assuming the nonrclativistic approximation for the Upsilon wave function, and with skewing corrections incorporated.

Automated summary

The cross section for exclusive Upsilon ultraperipheral photoproduction is determined using experimental measurements and calculated predictions, taking into account various factors such as parton distribution, wave function approximation, and skewing corrections.
