Abstract
The cross section for exclusive $\mathrm{\ensuremath{\Upsilon}}$ ultraperipheral photoproduction at present and future colliders is determined using the low $x$ gluon parton distribution function extracted from an analysis of exclusive $J/\ensuremath{\psi}$ 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 $\ensuremath{\gamma}p$ centre-of-mass energy range, calculated assuming the nonrelativistic approximation for the $\mathrm{\ensuremath{\Upsilon}}$ wave function, and with skewing corrections incorporated.
