The cross section for exclusive Υ ultraperipheral photoproduction at present and future colliders is determined using the low x gluon parton distribution function extracted from an analysis of exclusive J/ψ 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 γp centre-of-mass energy range, calculated assuming the nonrelativistic approximation for the Υ wave function, and with skewing corrections incorporated.
