摘要
The cross section for exclusive psi(2S) ultraperipheral production at the LHC is calculated using gluon parametrizations extracted from exclusive J/psi measurements performed at HERA and the LHC. Predictions are given at leading and next-to-leading order for pp centre-of-mass energies of 7, 8 and 14 TeV, assuming the non-relativistic approximation for the psi(2S) wave function.
