### Description

Both the energy and momentum transfer dependence of vector meson photoproduction off the proton are promising signatures of gluon saturation. In this talk, the momentum dependence of exclusive vector mesons such as $\rho^{0}$ and $\Upsilon$ photoproduction will be presented. The $\rho^{0}$ cross section measurement will be presented for $t$ values above 0.5 GeV for the first time, which was never measured for photoproduced $\rho^{0}$ mesons at HERA. In this talk, the experimental technique developed to measure high $t$ values, which required assessing the proton dissociation background, will be discussed. This method might have important implications for future analyses at the LHC and in future experimental facilities such as the Electron-Ion Collider.
