Description
Recently ATLAS published new data on dilepton angular coefficients in Z-boson production at the energy 8 TeV. In particular the famous Lam-Tung relation was shown to be broken and NNLO QCD corrections could explain only a fraction of this phenomenon. We investigate properties of the dilepton angular distributions and Lam-Tung relation breaking within kT-factorization framework and confront predictions of several models with ATLAS data.
