Observable phi-eta-star at LHC and second-order QED matrix element in Z/gamma to l+ l- decays

In a recent publication by ATLAS collaboration a new observable, the so-called phi-star angle, was used for precise measurement of transverse Z momentum. One of the dominant systematic errors for this measurement originates from the theoretical control of QED final-state bremsstrahlung. At present,...
