Measurement of the Drell-Yan triple-differential cross section in pp collisions at √s=8 TeV

Popis výsledku v původním jazyce

This paper presents a measurement of the triple-differential cross section for the Drell-Yan process Z/γ∗ → ℓ+ ℓ− where ℓ is an electron or a muon. The measurement is performed for invariant masses of the lepton pairs, mℓℓ , between 46 and 200 GeV using a sample of 20.2 fb−1 of pp collisions data at a centre-of-mass energy of s√=8 TeV collected by the ATLAS detector at the LHC in 2012. The data are presented in bins of invariant mass, absolute dilepton rapidity, |yℓℓ|, and the angular variable cos θ∗ between the outgoing lepton and the incoming quark in the Collins-Soper frame. The measurements are performed in the range |yℓℓ | < 2.4 in the muon channel, and extended to |yℓℓ | < 3.6 in the electron channel. The cross sections are used to determine the Z boson forward-backward asymmetry as a function of |yℓℓ | and mℓℓ .
