Abstract

AbstractThe cross-sections of $$\psi {(2S)}$$ψ(2S) meson production in proton-proton collisions at $$\sqrt{s} =13\text { TeV} $$s=13TeV are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of $$275\text { pb} ^{-1} $$275pb-1. The production cross-sections for prompt $$\psi {(2S)}$$ψ(2S) mesons and those for $$\psi {(2S)}$$ψ(2S) mesons from b-hadron decays ($${\psi {(2S)}} \text{-from- }{b} $$ψ(2S)-from-b) are determined as functions of the transverse momentum, $$p_{\mathrm {T}}$$pT, and the rapidity, y, of the $$\psi {(2S)}$$ψ(2S) meson in the kinematic range $$2<p_{\mathrm {T}} <20\text { GeV/}c $$2<pT<20GeV/c and $$2.0<y<4.5$$2.0<y<4.5. The production cross-sections integrated over this kinematic region are $$\begin{aligned} \begin{aligned}&\sigma (\text{ prompt } {\psi {(2S)}},13\text { TeV})\\&\quad =1.430\pm 0.005\text { (stat)} \pm 0.099\text { (syst)} \,\upmu \text {b} ,\\&\sigma ({\psi {(2S)}} \text{-from- }{b},13\text { TeV})\\&\quad =0.426\pm 0.002\text { (stat)} \pm 0.030\text { (syst)} \,\upmu \text {b} . \end{aligned} \end{aligned}$$σ(promptψ(2S),13TeV)=1.430±0.005(stat)±0.099(syst)μb,σ(ψ(2S)-from-b,13TeV)=0.426±0.002(stat)±0.030(syst)μb.A new measurement of $$\psi {(2S)}$$ψ(2S) production cross-sections in pp collisions at $$\sqrt{s}=7\text { TeV} $$s=7TeV is also performed using data collected in 2011, corresponding to an integrated luminosity of $$614\text { pb} ^{-1} $$614pb-1. The integrated production cross-sections in the kinematic range $$3.5<p_{\mathrm {T}} <14\text { GeV/}c $$3.5<pT<14GeV/c and $$2.0<y<4.5$$2.0<y<4.5 are $$\begin{aligned} \begin{aligned}&\sigma (\text{ prompt } {\psi {(2S)}},7\text { TeV})\\&\quad =0.471\pm 0.001\text { (stat)} \pm 0.025\text { (syst)} \,\upmu \text {b} ,\\&\sigma ({\psi {(2S)}} \text{-from- }{b},7\text { TeV})\\&\quad =0.126\pm 0.001\text { (stat)} \pm 0.008\text { (syst)} \,\upmu \text {b} . \end{aligned} \end{aligned}$$σ(promptψ(2S),7TeV)=0.471±0.001(stat)±0.025(syst)μb,σ(ψ(2S)-from-b,7TeV)=0.126±0.001(stat)±0.008(syst)μb.All results show reasonable agreement with theoretical calculations.
