Description
The production of Quarkonium is an important testing ground for QCD calculations. The J/
psi and Upsilon production cross-sections are measured in proton-proton collisions at the
ATLAS detector. Differential cross sections as a function of transverse momentum and
pseudorapidity will be presented. The fraction of J/\psi produced in $B$-hadron decays are
also measured and the differential production cross-sections of prompt and non-prompt J/
\psi determined separately. Results are compared to predictions from perturbative QCD
calculations.
