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

Understand

We report on the inclusive production cross sections of J/$\psi$, $\psi$(2S), $\Upsilon$(1S), $\Upsilon$(2S) and $\Upsilon$(3S), measured at forward rapidity with the ALICE detector in 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 1.28 pb$^{-1}$.
• Quarkonia are reconstructed in the dimuon-decay channel.
• The differential production cross sections are measured as a function of the transverse momentum $p_{\rm T}$ and rapidity $y$, over the $p_{\rm T}$ ranges $0<p_{\rm T}<20$ GeV/$c$ for J/$\psi$, $0<p_{\rm T}<12$ GeV/$c$ for all other resonances, and for $2.5<y<4$.
