Measurement of hard double-parton interactions with the ATLAS detector

Abstract

The production of W boson in association with two jets in proton-proton collisions at the LHC with a centre-of-mass energy of $\sqrt{s}$ = 7 TeV has been investigated using data collected with the ATLAS detector. The fraction of events arising from double-parton scattering has been measured through the transverse momentum balance between the two jets. The measurement provides new information on the scaling of the rate of double-parton scattering processes and constraints on proton transverse profile modeling.
