Abstract

We presented the exclusive photoproduction of Upsilon(1S,2S,3S) in pp and pA reactions at the LHC energies for Ultra Peripheral Collisions(UPC). It was calculated in the dipole formalism, with the dipoles models: GBW, CGC and b-CGC. The dipole formalism is characterised by a saturation effect, e.g, the mimic gluon distribution becomes saturated at low-x. This approach has shown a good agreement with the experimental data since HERA and with recent data released by LHCb for processes involving [Formula: see text], [Formula: see text], [Formula: see text] for UPC in pp.
