Higgs boson to four electrons in CMS - full simulation

Many decay channels will be exploited to search for the Higgs boson at the LHC. One of the most important channels is H → ZZ → 4e, where below the 2Mz threshold one or both Zs could be off mass shell. In this paper the signal and the main background processes are evaluated using recent theoretical predictions. Electron reconstruction is then presented, with dedicated algorithms developed for specific problems expected at the CMS experiment. Finally these algorithms are used to reconstruct the Higgs boson and thus to estimate its observability in CMS through this decay channel. (author)
