Search for gluon saturation in proton-lead collisions at $\sqrt{s_{NN}}=5.02$ TeV with the very forward CASTOR calorimeter at the CMS experiment / Van De Klundert, Merijn
An experimental search for signals of gluon saturation in proton-lead collisions at the CMS experiment is pursued. First, the theory behind the concept of gluon saturation is introduced [...]
