Quarkonia Production with the ATLAS Experiment

ATLAS has a wide program to study the production cross section and decay properties of the charmonium and bottomonium states. This presentation will cover ATLAS results in the domain of charmonium production, including J/psi, psi(2s) and chi_c states, as well as exotic state X(3872) and search for its bottomonium couterpart X_b in several possible decay channels. We also review the studies of di-J/psi and associated vector boson + J/psi production. These rare production modes provide novel insight into the mechanisms of charmonium production and the impact of proton structure on these observables.
