Abstract
Proc. of DIS 2012, 873-876; DESY
The production of Quarkonium is an important testing ground for QCD
calculations. The J/$\psi$ and $\Upsilon$(1S) production cross-sections
are measured in proton-proton collisions at the ATLAS detector at
the LHC. Differential cross sections as a function of transverse momentum
and rapidity have been measured. Charmonium states $\chi_{c1}$(1P)
and $\chi_{c2}$(1P) have been observed through radiative decays, as
well as a new $\chi_{b}$ state. Results are compared to perturbative
QCD predictions.
