Inclusive quarkonium production at forward rapidity in pp collisions at $$\mathbf {\sqrt{s}=8}~$$TeV

We report on the inclusive production cross sections of \({\mathrm{J}/\psi }\), \({\psi (\mathrm{2S})}\), \(\mathrm{\Upsilon }\)(1S), \(\mathrm{\Upsilon }\)(2S) and \(\mathrm{\Upsilon }\)(3S), measured at forward rapidity with the ALICE detector in \(\mathrm{pp}\) collisions at a center-of-mass energy \(\sqrt{s}=8\) TeV. The analysis is based on data collected at the LHC and corresponds to an integrated luminosity of 1.23 pb\(^{-1}\). Quarkonia are reconstructed in the dimuon-decay channel. The differential production cross sections are measured as a function of the transverse momentum \({p_\mathrm{T}}\) and rapidity y, over the \({p_\mathrm{T}}\) ranges \(0<{p_\mathrm{T}}<20\) GeV/c for \({\mathrm{J}/\psi }\), \(0<{p_\mathrm{T}}<12\) GeV/c for all other resonances, and for \(2.5更多
