Higgs boson to 4 Electrons in CMS Full Simulation

Many decay channels can be exploited to search for the Higgs boson at the LHC. One of the most important channel is $H ightarrow ZZ rightarrow 4e, where below the 2M_{Z} threshold one or both Zs could be off the mass shell. In this paper we first evaluate the signal and the main background processes 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 to estimate its observability in CMS through this decay channel.
