Abstract
A wide program of studies of heavy flavour production at the LHC is performed with the ATLAS detector, including charm and beauty hadrons, quarkonia production in both flavours, and associated production of J/ψ + W, J/ψ + Z and J/ψ + J/ψ. This report will cover recent results, and discuss in particular the results on X(3872) and J/ψ+J/ψ production, based on the data collected at 8 TeV. For the X(3872) production measurement, an enhancement in the non-prompt production at low pT, and of a shorter effective lifetime, is observed. The enhancement might be related to the production of Bc state that decays inclusively to X(3872). The differential J/ψ + J/ψ cross-section is measured and the fraction of prompt pair events due to double parton scattering is determined by studying kinematic correlations. The total and double parton scattering cross-sections are compared with predictions.
