Studies of double parton scattering in ATLAS
@article{Lobodzinska2017StudiesOD, title={Studies of double parton scattering in ATLAS}, author={Ewelina Maria Lobodzinska}, journal={arXiv: High Energy Physics - Experiment}, year={2017} }
In this contribution, Double Parton Scattering processes observed with the ATLAS detector at LHC are discussed. Results of five analyses are presented: production of W boson in association with 2 jets, production of J/psi meson in association with W boson, J/psi production with Z boson, J/psi pair production and four jet events.
