Abstract
<p>Measurements of prompt ψ(2S) meson production cross sections in proton–lead (pPb) and proton–proton (pp) collisions at a nucleon–nucleon center-of-mass energy of s<sub>NN</sub>=5.02TeV are reported. The results are based on pPb and pp data collected by the CMS experiment at the LHC, corresponding to integrated luminosities of 34.6 nb<sup>−1</sup> and 28.0 pb<sup>−1</sup>, respectively. The nuclear modification factor R<sub>pPb</sub> is measured for prompt ψ(2S) in the transverse momentum range 4<p<sub>T</sub><30GeV/c and the center-of-mass rapidity range −2.4<y<sub>CM</sub><1.93. The results on ψ(2S) R<sub>pPb</sub> are compared to the corresponding modification factor for prompt J/ψ mesons. The results point to different nuclear effects at play in the production of the excited charmonium state compared to the ground state, in the region of backward rapidity and for p<sub>T</sub><10GeV/c.</p>
