Abstract

The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at [Formula: see text] 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
