Abstract	This paper presents the studies of the background contribution to the $H \rightarrow 4l$ searches originating from the processes of virtual photon emissions and conversions accompanying the production of $Z/ \gamma ^*$-bosons at the LHC. They extend the studies of the irreducible background presented in the ATLAS and CMS Higgs papers by including the quark--gluon collision processes, on top of the quark--antiquark ones, and by taking into account the emissions of virtual photons by the parton showers.
