Abstract
At the LHC a precise measurement of the Higgs boson mass (if discovered), at the level of 0.1-1%, will be possible through the channel gg → H → 4l for a wide range of Higgs mass values. To match such an accuracy, the systematic effects induced by QED corrections need to be investigated. In the present study the calculation of O(α) and higher order QED corrections is illustrated as well as their impact on the Higgs mass determination, once realistic event selections for charged leptons and photons are considered.File in questo prodotto:
