Abstract
We report on the inclusive production cross sections of (Formula presented.) , (Formula presented.) , (Formula presented.) (1S), (Formula presented.) (2S) and (Formula presented.) (3S), measured at forward rapidity with the ALICE detector in (Formula presented.) collisions at a center-of-mass energy (Formula presented.) TeV. The analysis is based on data collected at the LHC and corresponds to an integrated luminosity of 1.23 pb (Formula presented.). Quarkonia are reconstructed in the dimuon-decay channel. The differential production cross sections are measured as a function of the transverse momentum (Formula presented.) and rapidity y, over the (Formula presented.) ranges (Formula presented.) GeV/c for (Formula presented.) , (Formula presented.) GeV/c for all other resonances, and for (Formula presented.). The cross sections, integrated over (Formula presented.) and y, and assuming unpolarized quarkonia, are (Formula presented.) (Formula presented.) b, (Formula presented.) (Formula presented.) b, (Formula presented.) nb, (Formula presented.) nb and (Formula presented.) nb, where the first uncertainty is statistical and the second one is systematic. These values agree, within at most (Formula presented.) , with measurements performed by the LHCb collaboration in the same rapidity range.
