Measurement of psi(2S) meson production in pp collisions at root s = 7 TeV

The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at √s = 7 TeV has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb -1. The ψ(2S) mesons are reconstructed in the decay channels ψ(2S)→μ +μ - and ψ(2S)→J/...

Summary:The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at √s = 7 TeV has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb -1. The ψ(2S) mesons are reconstructed in the decay channels ψ(2S)→μ +μ - and ψ(2S)→J/ψπ +π -, with the J/ψ meson decaying into two muons. Results are presented both for promptly produced ψ(2S) mesons and for those originating from b-hadron decays. In the kinematic range p T(ψ(2S))≤16 GeV/c and 2
