Prompt and nonprompt ψ(2S) production in pPb collisions at sNN = 8.16 TeV Comerma Montells, Albert Garcia Moreno, Paula Garrido Beltrán, Lluís Gioventù, Alessandra Gironella Gironell, Pere Gomez Fernandez, Sergio Graugés Pous, Eugeni Lobo Salvia, Aniol López Huertas, Albert Manera Escalero, Rafel Marin Benito, Carla Mauricio Ferre, Joan Alfonso Albero, Alejandro Vazquez Gomez, Ricardo LHCb Collaboration Cromodinàmica quàntica Hadrons Física de partícules Quantum chromodynamics Hadrons Particle physics  The production of ψ(2S) mesons in proton-lead collisions at a centre-of-mass energy per nucleon pair of √ sNN = 8.16 TeV is studied with the LHCb detector using data corresponding to an integrated luminosity of 34 nb−1 . The prompt and nonprompt ψ(2S) production cross-sections and the ratio of the ψ(2S) to J/ψ cross-section are measured as a function of the meson transverse momentum and rapidity in the nucleon-nucleon centre-ofmass frame, together with forward-to-backward ratios and nuclear modifcation factors. The production of prompt ψ(2S) is observed to be more suppressed compared to pp collisions than the prompt J/ψ production, while the nonprompt productions have similar suppression factors. 2025-07-04T14:50:26Z 2025-07-04T14:50:26Z 2024 2025-07-04T14:50:26Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1007/JHEP04(2024)111 Journal of High Energy Physics, 2024, vol. 2024, num.111 https://doi.org/10.1007/JHEP04(2024)111 cc-by (c) Aaij, R. et al., 2024 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
