Energy-dependent hotspots model via vector meson photoproduction
Original language description
We present a model for the QCD structure of hadrons as seen in the dipole picture. The model is based on hot spots -- regions of large gluonic density -- populating the impact parameter space. In our model, the number of hot spots grows with energy and their positions fluctuate event-by-event.Using this model, we calculate coherent and incoherent photoproduction of vector mesons (VM) off a proton and nuclear targets. We compare our predictions with current data from HERA, RHIC and the LHC at different energies. We also present new signatures of saturation effects that could be observed with current and future data.
