Study of ψ(2S) production and cold nuclear matter effects in pPb collisions at $$\sqrt{s_{NN}}$$
The production of ψ(2S) mesons is studied in dimuon final states using proton-lead (pPb) collision data collected by the LHCb detector. The data sample corresponds to an integrated luminosity of 1.6 nb–1. The nucleon-nucleon centre-of-mass energy of the pPb collisions is $$\sqrt{s_{NN}}$$ = 5 TeV. The measurement is performed using ψ(2S) mesons with transverse momentum less than 14 GeV/c and rapidity y in the ranges 1.5 < y < 4.0 and –5.0 < y < –2.5 in the nucleon-nucleon centre-of-mass system. The forward-backward production ratio and the nuclear modification factor are determined for ψ(2S) mesons. Using the production cross-section results of ψ(2S) and J/ψ mesons from b-hadron decays, the $$b\bar{b}$$ cross-section in pPb collisions at $$\sqrt{s_{NN}}$$ = 5 TeV is obtained.
