Abstract

The production of inclusive, prompt and non-prompt J/ψ was studied for the first time at midrapidity (−1.37 < y <inf>cms</inf> < 0.43) in p-Pb collisions at sNN = 8.16 TeV with the ALICE detector at the LHC. The inclusive J/ψ mesons were reconstructed in the dielectron decay channel in the transverse momentum (p <inf>T</inf>) interval 0 < p <inf>T</inf> < 14 GeV/c and the prompt and non-prompt contributions were separated on a statistical basis for p <inf>T</inf> > 2 GeV/c. The study of the J/ψ mesons in the dielectron channel used for the first time in ALICE online single-electron triggers from the Transition Radiation Detector, providing a data sample corresponding to an integrated luminosity of 689 ± 13 μb<sup> −1</sup>. The proton-proton reference cross section for inclusive J/ψ was obtained based on interpolations of measured data at different centre-of-mass energies and a universal function describing the p <inf>T</inf>-differential J/ψ production cross sections. The p <inf>T</inf>-differential nuclear modification factors R <inf>pPb</inf> of inclusive, prompt, and non-prompt J/ψ are consistent with unity and described by theoretical models implementing only nuclear shadowing.
