The pPb differential cross-sections of prompt J/? are shown in a wide kinematic region, for transverse momentum pT spanning from 2 to 30 GeV/c and a rapidity interval between -2.4 to 1.93 in the center of mass of the collision. The final results on prompt ?(2S) meson production cross section in pp and pPb collisions at 5.02 TeV are also reported as a function of pT and rapidity, for pT from 4 to 30 GeV/c. The nuclear modification factor is found to be smaller than that of prompt J/? in all measured bins, especially at low pT and at backward rapidity. Such a different behaviour between the ground and excited states cannot be reproduced considering nPDF effects alone.enQuarkoniaCharmoniaPrompt J/ψPrompt ψ(2S)ProductionArticle10.1016/j.nuclphysa.2018.10.028Q2WOS:000457515500171Q3
