Measurement of

The cross-sections of $$\psi {(2S)}$$ meson production in proton-proton collisions at $$\sqrt{s} =13\text { TeV} $$ are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of $$275\text { pb} ^{-1} $$. The production cross-sections for prompt $$\psi {(2S)}$$ mesons and those for $$\psi {(2S)}$$ mesons from b-hadron decays ($${\psi {(2S)}} \text{-from- }{b} $$) are determined as functions of the transverse momentum, $$p_{\mathrm {T}}$$, and the rapidity, y, of the $$\psi {(2S)}$$ meson in the kinematic range $$2<p_{\mathrm {T}} <20\text { GeV/}c $$ and $$2.0<y<4.5$$. The production cross-sections integrated over this kinematic region are $$\begin{aligned} \begin{aligned}&\sigma (\text{ prompt } {\psi {(2S)}},13\text { TeV})\\&\quad =1.430\pm 0.005\text { (stat)} \pm 0.099\text { (syst)} \,\upmu \text {b} ,\\&\sigma ({\psi {(2S)}} \text{-from- }{b},13\text { TeV})\\&\quad =0.426\pm 0.002\text { (stat)} \pm 0.030\text { (syst)} \,\upmu \text {b} . \end{aligned} \end{aligned}$$A new measurement of $$\psi {(2S)}$$ production cross-sections in pp collisions at $$\sqrt{s}=7\text { TeV} $$ is also performed using data collected in 2011, corresponding to an integrated luminosity of $$614\text { pb} ^{-1} $$. The integrated production cross-sections in the kinematic range $$3.5<p_{\mathrm {T}} <14\text { GeV/}c $$ and $$2.0<y
