Possibilities of ttbarH0 Event Reconstruction

A light Standard Model Higgs boson can be produced in association with tt in the process pp -> ttH and detected in the final state b b b b q q l nu. The cross section of this channel is not large, but there are only few sources of Standard Model background with similar event structures. Here we investigate how the correct b jets can be selected in view of Higgs mass reconstruction. We discuss three methods of event reconstruction, a background suppression method for tt+jets background events, and the effects of jet energy resolution smearing.
