Quarkonium production as a probe of double parton scattering at ATLAS

Associated quarkonium events can be produced from single parton scattering (SPS) or from two independent parton-parton scatters in a single proton-proton collision, known as double parton scattering (DPS). Although the SPS is dominant, it is expected that DPS plays a larger role at high energies and could be increasingly important for associated quarkonium production.
