Abstract

The production cross-sections of Υ mesons, namely Υ(1S), Υ(2S) and Υ(3S), in pp collisions at √s = 5 TeV are measured with a data sample corresponding to an integrated luminosity of 9.13 ± 0.18 pb⁻¹ collected by the LHCb detector. The Υ mesons are reconstructed in the decay mode Υ → μ⁺μ⁻. Double differential cross-sections times branching fractions, as functions of the transverse momentum p_T and the rapidity y of the Υ mesons, are measured in the range p_T < 20 GeV/c and 2.0 < y < 4.5. The results integrated over these p_T and y ranges are

σ(Υ(1S))×B(Υ(1S)→μ⁺μ⁻)=2101±33±83pb,
σ(Υ(2S))×B(Υ(2S)→μ⁺μ⁻)=526±20±21pb,
σ(Υ(3S))×B(Υ(3S)→μ⁺μ⁻)=242±16±10pb,

where the first uncertainties are statistical and the second are systematic. The ratios of cross-sections between measurements of two different Υ states and between measurements at different centre-of-mass energies are determined. The nuclear modification factor of Υ(1S) at √s = 5 TeV is updated as well using the directly measured cross-section results from this analysis.

N2 - The production cross-sections of Υ mesons, namely Υ(1S), Υ(2S) and Υ(3S), in pp collisions at √s = 5 TeV are measured with a data sample corresponding to an integrated luminosity of 9.13 ± 0.18 pb−1 collected by the LHCb detector. The Υ mesons are reconstructed in the decay mode Υ → μ+μ−. Double differential cross-sections times branching fractions, as functions of the transverse momentum pT and the rapidity y of the Υ mesons, are measured in the range pT < 20 GeV/c and 2.0 < y < 4.5. The results integrated over these pT and y ranges areσ(Υ(1S))×B(Υ(1S)→μ+μ−)=2101±33±83pb,σ(Υ(2S))×B(Υ(2S)→μ+μ−)=526±20±21pb,σ(Υ(3S))×B(Υ(3S)→μ+μ−)=242±16±10pb,where the first uncertainties are statistical and the second are systematic. The ratios of cross-sections between measurements of two different Υ states and between measurements at different centre-of-mass energies are determined. The nuclear modification factor of Υ(1S) at √s = 5 TeV is updated as well using the directly measured cross-section results from this analysis.
