Measurement of psi (2S) production cross-sections in proton-proton collisions at v s=7 and 13 TeV

The cross-sections of ψ(2S) meson production in proton-proton collisions at √ s = 13 TeV are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of 275 pb−1. The production cross-sections for prompt ψ(2S) mesons and those for ψ(2S) mesons from b-hadro...
