Description
We present new measurements of the associated production of quarkonium
with a vector boson or an additional quarkonium state using the ATLAS
Run-1 dataset. These rare processes provide new insight into QCD
models of quarkonium production, but also provide new opportunities to
study double parton scattering, including cross-section measurements
in single and double parton scattering dominated regimes and a precise
assessment of the sigma_eff parameter governing the effective spatial
area of parton-parton interactions at a variety of energy scales.
