Study of the hard double-parton scattering contribution to inclusive four-lepton production in pp collisions at s=8 TeV with the ATLAS detector
(2019) In Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 790. p.595-614- Abstract
- The inclusive production of four isolated charged leptons in pp collisions is analysed for the presence of hard double-parton scattering, using 20.2 fb −1 of data recorded in the ATLAS detector at the LHC at centre-of-mass energy s=8 TeV. In the four-lepton invariant-mass range of 80<m 4ℓ <1000 GeV, an artificial neural network is used to enhance the separation between single- and double-parton scattering based on the kinematics of the four leptons in the final state. An upper limit on the fraction of events originating from double-parton scattering is determined at 95% confidence level to be f DPS =0.042, which results in an estimated lower limit on the effective cross section at 95% confidence level of 1.0 mb. © 2019 The Author(s)
