“…This has indeed been confirmed in photoproduction in the HERA energy range, where e.g. b ρ 0 > b J/ψ was measured [13,14]. Since the radius of the ψ(2S) meson is approximately a factor of two larger than that of the J/ψ meson one might naively expect a steeper t dependence.…”

Using the theoretical approaches describing well the available data on t-integrated coherent photoproduction of light and heavy vector mesons in Pb-Pb UPCs at the LHC in Run 1, we calculate the momentum transfer distributions for this process for ρ and J/ψ vector mesons in the kinematics of Run 2 at the LHC. We demonstrate that nuclear shadowing not only suppresses the absolute value of the cross sections, but also shifts the momentum transfer distributions toward smaller values of the momentum transfer |t|. This result can be interpreted as a broadening in the impact parameter space of the effective nucleon density in nuclei by 14% in the case of ρ and the nuclear gluon distribution by 5 − 11% in the case of J/ψ.

The first measurement of exclusive photoproduction of ρ 0 mesons associated with leading neutrons at HERA is presented. The data are taken with the H1 detector in the years 2006-2007 at √ s = 319 GeV and correspond to an integrated luminosity of 1.16 pb −1 . ρ 0 mesons are reconstructed from their decays to pions in the central tracking chamber, while leading neutrons carrying a large fraction of the incoming proton momentum, x L > 0.35, are detected in the Forward Neutron Calorimeter. The phase space of the measurement is defined by the photon virtuality Q 2 < 2 GeV 2 , the total energy of the photon-proton system 20 < W γp < 100 GeV and the polar angle of the leading neutron, θ n < 0.75 mrad. The cross section of the reaction γ p → ρ 0 nY , where Y is a small mass system escaping undetected in the proton direction, is measured as a function of the neutron energy, of the effective mass of the π + π − system as well as of the transverse momentum squared, p 2 t , and of the pseudorapidity η of ρ meson. The data are interpreted in terms of the double peripheral process, involving pion exchange at the proton vertex followed by elastic photoproduction of a ρ meson on the virtual pion. In the framework of OPE approach elastic cross section of photon-pion scattering, σ el (γπ + → ρ 0 π + ) at average energy W γπ = 22 GeV is extracted.
