Title: Measurement of prompt $$\psi$$(2S) production cross sections in proton-lead and proton-proton collisions at $$\sqrt{s_{_\mathrm{NN}}}=$$ 5.02 TeV

Abstract

Measurements of prompt $$\psi$$(2S) meson production cross sections in proton-lead (pPb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of $$\sqrt{s_{_\mathrm{NN}}}=$$ 5.02 TeV 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$$^{-1}$$ and 28.0 pb$$^{-1}$$, respectively. The nuclear modification factor $$R_\mathrm{pPb}$$ is measured for prompt $$\psi$$(2S) in the transverse momentum range 4 $<$ p$$_\mathrm{T}$$ $<$ 30 GeV$/c$ and the center-of-mass rapidity range $-$2.4 $$< y_\mathrm{cm} <$$ 1.93. The results on $$\psi$$(2S) $$R_\mathrm{pPb}$$ are compared to the corresponding modification factor for prompt J$$/\psi$$ mesons and are found to be more suppressed than the J$$/\psi$$ states over the entire kinematic range studied.
