Measurement of the W → μν cross-sections as a function of the muon transverse momentum in pp collisions at 5.02 TeV

The pp → W±(→ μ±νμ)X cross-sections are measured at a proton-proton centre-of-mass energy $$ \sqrt{s}=5.02 $$TeV using a dataset corresponding to an integrated luminosity of 100 pb−1 recorded by the LHCb experiment. Considering muons in the pseudorapidity range 2.2 < η < 4.4, the cross-section...

Description
Summary:The pp → W±(→ μ±νμ)X cross-sections are measured at a proton-proton centre-of-mass energy $$ \sqrt{s}=5.02 $$TeV using a dataset corresponding to an integrated luminosity of 100 pb−1 recorded by the LHCb experiment. Considering muons in the pseudorapidity range 2.2 < η < 4.4, the cross-sections are measured differentially in twelve intervals of muon transverse momentum between 28 < pT < 52 GeV. Integrated over pT, the measured cross-sections areσW+→μ+νμ=300.9±2.4±3.8±6.0pb,σW−→μ−ν¯μ=236.9±2.1±2.7±4.7pb,$$ {\displaystyle \begin{array}{c}{\sigma}_{W^{+}\to {\mu}^{+}{\nu}_{\mu }}=300.9\pm 2.4\pm 3.8\pm 6.0\ \textrm{pb},\\ {}{\sigma}_{W^{-}\to {\mu}^{-}{\overline{\nu}}_{\mu }}=236.9\pm 2.1\pm 2.7\pm 4.7\ \textrm{pb},\end{array}} $$
