Abstract

Inclusive J/ψ production is studied in p-Pb interactions at a centre-of-mass energy per nucleon-nucleon collision sqrt{s_{mathrm{NN}}}=8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay to a muon pair, in the centre-of-mass rapidity intervals 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, where positive and negative ycms refer to the p-going and Pb-going direction, respectively. The transverse momentum coverage is pT < 20 GeV/c. In this paper, ycms- and pT-differential cross sections for inclusive J/ψ production are presented, and the corresponding nuclear modification factors RpPb are shown. Forward results show a suppression of the J/ψ yield with respect to pp collisions, concentrated in the region pT ≲ 5 GeV/c. At backward rapidity no significant suppression is observed. The results are compared to previous measurements by ALICE in p-Pb collisions at sqrt{s_{mathrm{NN}}}=5.02 TeV and to theoretical calculations. Finally, the ratios RFB between forward- and backward-ycmsRpPb values are shown and discussed.

Highlights

√ by ALICE in p–Pb collisions at sNN = 5.02 TeV and to theoretical calculations
We report ALICE results on cross sections and nuclear modification √
The analysis presented here is based on the detection of muons in the ALICE forward muon spectrometer [50], which includes five tracking stations (Cathode Pad Chamber detectors), followed by two triggering stations (Resistive Plate Chamber detectors)

Summary

Introduction

Factors for inclusive J/ψ production in p–Pb collisions at sNN = 8.16 TeV, in the rapidity regions 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, and for pT < 20 GeV/c. The estimated value of the systematic uncertainty on the tracking efficiency is 1% (2%) for pT-integrated J/ψ production in p–Pb (Pb–p) collisions, and shows no appreciable dependence on the dimuon kinematics.
