Abstract

We investigate the forward-jet energy spectrum within the color glass condensate framework at 5 TeV center-of-mass energy. In particular, we focus on the kinematic range covered by the CMS-CASTOR calorimeter. We show that our saturation-model calculations are compatible with the CASTOR measurements and that to optimally reproduce the data, effects of multiparton interactions need to be included. We predict a significant nuclear suppression—reaching down to 50% at the lowest considered jet energies Ejet∼500 GeV.
