A measurement of angular correlations in Drell–Yan lepton pairs via the ϕη⁎ observable is presented. This variable probes the same physics as the Z/γ⁎ boson transverse momentum with a better experimental resolution. The Z/γ⁎→e+e− and Z/γ⁎→μ+μ− decays produced in proton–proton collisions at a centre-of-mass energy of s=7 TeV are used. The data were collected with the ATLAS detector at the LHC and correspond...
We present a new measurement of the Z/γ∗ transverse momentum distribution in the range 0–330 GeV, in proton–antiproton collisions at s=1.96 TeV. The measurement uses 0.97 fb −1 of integrated luminosity recorded by the D0 experiment and is the first using the Z/γ∗→μ+μ−+X channel at this center-of-mass energy. This is also the first measurement of the Z/γ∗ transverse momentum distribution that...
