Measurement of prompt psi(2S) production cross sections in proton-lead and proton-proton collisions at root s(NN)=5.02 TeV
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 √sNN = 5.02 TeV are reported. The results are based on pPb and pp data collected by the CMS experiment at the LHC, corresponding to inte...

| description | 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 √sNN = 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 RpPb is measured
for prompt ψ(2S) in the transverse momentum range 4 < pT < 30 GeV/c and the center-of-mass rapidity
range −2.4 < yCM < 1.93. The results on ψ(2S) RpPb 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
pT < 10 GeV/c |
