"Silver" mode for heavy Higgs search in the presence of a fourth SM family

Abstract

We investigate the possible enhancement to the discovery of the heavy Higgs boson through the possible fourth standard model family heavy neutrino. Using the channel $h\rightarrow\nu_4\bar{\nu}_4 \rightarrow \mu W \mu W \to \mu j j\mu j j$ it is found that for certain ranges of the Higgs boson and $\nu_4$ masses, LHC could discover both of them simultaneously with $1fb^{-1}$ integrated luminosity.
