Recent Results on Quarkonium and Beauty Production in pp collisions with the ATLAS Detector

The latest results from ATLAS on heavy flavour and quarkonium production, including exotic states, are presented. This talk includes the measurement of B-hadron pair production, presented as a function of a variety kinematic variables between the two B-hadrons, providing important inputs to modelling of production via gluon splitting. Additional Insight into QCD models of quarkonium production and double parton scattering is also presented, through the production cross-section measurement of di-Jpsi and effective cross-section from double parton scattering.
